Seed Words

If I have an electrum wallet on a destroyed cell phone and I don't have the seed words, am I screwed? Installed an electrum wallet on an ubuntu usb stick, and when I went to transfer the coins to a BitPay wallet. the electrum wallet wouldn't make the transfer because of missing script, or an update i couldn't get or something. So I created a wallet with the seed words in windows 10. I was able to get a QR code with the wallet in Windows 10 and transfer it to a wallet. I believe it is the electrum wallet I installed on my Android tablet which was destroyed the next day. How can I tell what wallet I transferred my bitcoin to? This is the transaction: https://blockchair.com/bitcoin/transaction/51dd2b92fc511e8f0dcc1e07ce83442033339f0d555f7d62564e47ee0ccdde80. My tablet and phone were destroyed and I am having no luck finding the right seed words. The sending wallets are still fine on windows 10, but I am at a loss.

What I currently use for privacy

So this is what software I currently use for privacy, would like some opinions if possible:
Starting with my cellphone, my device is a Google Pixel 3A XL with GrapheneOS flashed, I have the following apps installed:
F-Droid and AuroraOSS (as my app stores), NewPipe (youtube client), Vanadium (web browser), Tutanota and K-9 Mail (for e-mails), OsmAnd+ (for maps), Joplin (notes), Open Camera (camera), OpenBoard and Mozc for Android (Keyboard and Japanese Keyboard), Aegis Authenticator, KeePassDX (password manager), LibreTorrent (torrent client), Librera PRO (pdf/epub/mobi reader, I don't own a Kindle nor want to own one so I use my cellphone to read), Tachiyomi (manga reader), Signal (for messaging), Vinyl Music Player, VLC, Simple Gallery Pro and Simple Calendar Pro (I prefer them over stock Graphene options) and I also use Electrum and Samourai (Bitcoin Wallet) and Monerujo (Monero Wallet)
I also have OpenVPN (for VPN) and use a private DNS for ad and tracking blocking (provided by my VPN provider)
I have 3-4 PCs, will go over every single one of them:
my main PC is a desktop PC (that I built myself) that I mainly use for working and other tasks.
It runs Artix Linux (basically Arch Linux without systemd), I use UFW as my firewall (denying all incoming and also denying all outgoing only allowing what is useful) and I also use AppArmor Profiles, I disabled IPV6 and SWAP, configured my VPN connection as well on network settings and I currently run OpenVPN on my computer (my VPN provider allows for multi-hop cascade through OpenVPN in which I can create a custom VPN cascade up to four servers, each consecutive hop re-encrypts my traffic and assigns me a new IP address) and I've also set disk encryption on installation (have set in all of my computers)
As for software: I use Mozilla Firefox as my web browser (I set it to always be in private mode, unchecked suggestions for browsing history, bookmarks, and open tabs, I've also disabled the Firefox data collection in settings and block dangerous and deceptive content, I use DuckDuckGo as my search engine, I use Firefox Home as my default as my homepage. The rest of my tweaks were done in about:config (using privacytools.io site tweaks + geo.enabled = false, network.cookie.lifetimePolicy = 2 and dom.security.https_only_mode as true which are not listed on the site) and the only addons I use are uBlock Origin on Hard Mode and Decentraleyes), KeePassXC (password manager), VIM (use it as a Text Editor and as an IDE for coding), LibreOffice (for working stuff), GIMP (image editor), VLC, qBitTorrent and Tutanota's Desktop Client and Thunderbird (for e-mails)
I also use KVM/QEMU for virtual machines (usually in case I wanna test some distro or use Tails/Whonix)
For my gaming PC (also a desktop I've built myself) I run Manjaro KDE on it, the only apps I have in the system are Firefox (same settings as above), OBS and KVM/QEMU (which I use a Win10 virtual machine for games, there are tutorials on YouTube on how to do so if you're interested). I have the same firewall settings as above, using AppArmor as well and I've also disabled IPV6 and SWAP, I run OpenVPN on it as well as my VPN DNS settings on network settings. I also use different mouse and keyboard on both my PCs and never mix them together.
My other 2 PCs are both laptops, one is a Acer Aspire Nitro I've bought for work (in case I need to work while in a trip or if I wanna work outside etc), it has the same settings and programs as my main PC but I run Gentoo on it. The other laptop is an old ThinkPad that runs Slackware on it, but I rarely use it and this laptop is most of the times not with me for safety reasons.
For some other devices and stuff: I have an Asus RT-AC86U router with OpenWRT flashed on it that I also run OpenVPN config files (this one coming from another provider, I use two VPN providers, on in my PCs and the other in my router), I have a Ledger Nano S as a hardware wallet for both Bitcoin and Monero (most of my cryptocurrency is there, I use hardware wallet for hodling purposes and as my emergency funding) and I have LOTS of USB flash drivers (all of them for Linux Live ISOs purposes), I also have a Nintendo Switch Lite (only gaming console I have, although have not been playing that much on it recently) that I only connect to the internet in case I need to download some updates or play online and after I'm done I immediately disconnect it from the internet.
Some other privacy habits I have are:
I don't own any smart device like Smart TVs (I've been more than 10 years now without watching TV, doesn't even bother me), Smart Fridges or Dishwashers that connect to your internet, ROOMBAS, Smart Home etc, I keep all my money on crypto (and I have a small amount in gold as well, but I rarely invest on it, all my gold is stored in a manual safe here in my apartment) and I only have like, 10 bucks or so in my back account (as soon as I receive any money I just left the necessary in my account to pay bills and put all the rest on crypto, I try to pay everything on crypto or cash), I RARELY use cloud storage, but if I need to, I go with NextCloud and encrypt all my files with VeraCrypt before uploading it, all my VPN services were paid with Bitcoin (I try to pay everything with crypto as previously said) and I never write directly into any website, I usually write my text on a text editor, copy it and paste it on the website (needless to say that I don't use mainstream social media as well)
So, what do you guys think? anything that you would add your recommend me? (before anyone mentions about self-hosting a DNS server using Pi-hole on a Raspberry Pi, I'm actually thinking on doing it in a near future)
EDIT: forgot to mention that I don't watch YouTube on PC on youtube site, I mostly watch youtube's videos on invidio.us and only use the youtube site for watching live streams honestly. And I also barely go outside with my smartphone (only if I really need to) and I usually keep it away from my computers etc.
EDIT 2: also another thing: I covered all my laptop's webcams with black electrical tape, I have a Logitech C922 Pro webcam for my desktop PCs but rarely use it, and when I need to use it, I unplug it as soon as I'm done with it.

HowTo: Create and Spend a Electrum Segwit 3of3 Multisig wallet with Trezors

I wrote a simlar post in Bitcoin about creating a MS wallet without a Trezor, this guide will focus on creating a 3of3 MS wallet with three Trezor's. Hopefully it should be obvious how to extend this to N-of-M for any value of N or M. You can also use this as a blueprint to do MS with non-HW Electrum wallets like Android.
It should be noted that this is the most general case method for setting this up. This allows to replace non-HW Electrum wallets into this procedure where HW-wallets are referenced. For the far simpler method, just pick Cosign with hardware device instead of Cosign with key as I outline here. If you choose Cosign with HW you can do the entire process in one wallet file in one session.
The main advantage of multisig is that it reduces the risk of one compromised seed exposing all your funds. Although this is exceedingly complicated, the added layer of complications make it all the more difficult to compromise your funds. Most of the complexity is on the initial wallet setup. Sending is only a bit more complicated, and Receiving is the same as it would be for any electrum wallet.
We will be creating three wallets here, and each will use a Trezor with its own seed, passphrase, and public key (Zpub). If your just wanting to play with this process you could use one Trezor with three different passphrases. Electrum will treat this like three different wallets, since... well since it is. The Zpubs will be calculated by Electrum.
For all references to wallet passphrases or encryption passwords, I highly recommend you generate six-word passphrases. Three simple ways to construct a six-word passphrase would be to either use EFF diceware long wordlist to roll for 6 words, or create a short six-word BIP39 seed and use that as a passphrase, or create a random Electrum seed and use the last 6 words. You will need to take care that all six-word passphrases are equal or less than 50 characters. Longer passphrases can produce some unexpected results. Whenever you need to create a passphrase or password from here on out, create a six-word string as described above.
Assuming your have your Trezors initialized with passphrases enabled, our first order of business will be ensuring the authenticity of Electrum. For the PC's this must be done with PGP/GPG following the procedure spelled out on the Electrum website, or the secondary docs. It is absolutely critical that you are certain your using the correct ThomasV key. As of the time of this writing, the "correct" ThomasV key was:
ThomasV PGP: 6694 D8DE 7BE8 EE56 31BE D950 2BD5 824B 7F94 70E6
Once your Electrum install is validated, here is excruciating detail on creating and spending from a 3of3 multisig wallet. This assumes you have passphrases enabled on all your Trezors and that each has a unique name. For simplicity I will simply refer to their names at "trez-1", "trez-2", and "trez-3"

Three Wallet Creation passes

Do the following first for "trez-1", then for "trez-2" and finally for "trez-3". The order is VERY important:
  1. Wallet->New, name your wallet
  2. Then insert your Trezor ("trez-1", "trez-2", or "trez-3")
  3. Choose Multisig Wallet, then 3of3
  4. Choose Use a hardware device
  5. Select device
  6. Craft (and record) a new 6 word passphrase
  7. Choose Native Segwit derivation
  8. Record Zpub
  9. Unplug your Trezor ("trez-1", "trez-2", or "trez-3")
  10. Choose Add Cosigner Key
  11. Wait at "Add Cosigner 2" dialog

Distribute Zpubs to Finish Wallet Creation

When completing the setup for each wallet below you will be prompted for a wallet encryption password. I recommend you craft a unique six-word string as described above. If Electrum asks to reconnect to your HW wallet simply say "No". You will notice that the order is the reverse of the previous portion. As before, the order is VERY important,.
  1. Swap over to your trez-3 wallet
  2. Click "Enter Cosigner Key"
  3. Enter trez-1 Zpub
  4. Click "Enter Cosigner Key"
  5. Enter trez-2 Zpub
  6. Swap over to your trez-2 wallet
  7. Click "Enter Cosigner Key"
  8. Enter trez-3 Zpub
  9. Click "Enter Cosigner Key"
  10. Enter trez-1 Zpub
  11. Swap over to your trez-1 wallet
  12. Click "Enter Cosigner Key"
  13. Enter trez-2 Zpub
  14. Click "Enter Cosigner Key"
  15. Enter trez-3 Zpub
You can now close each wallet file.
You should now have recorded:
Keep the 12 secrets secure, separate and safe.

Receive funds into your 3of3 MS wallet

Receive just like any other wallet. All three wallets will watch the same set of addresses

Spend funds from your 3of3 MS wallet

  1. Create a TXN as you normally would on your first device
  2. In the TXN dialog hit "Preview" instead of Send
  3. In the Preview screen hit "Sign", then "Export"
  4. Copy the TXN over to your second device
  5. On your second device click Tools->Load Transaction
  6. Enter your partially signed TXN
  7. Verify the Status reads "Partially signed (1/3)"
  8. In the Preview screen hit "Sign", then "Export"
  9. Copy the TXN over to your third device
  10. On your third device click Tools->Load Transaction
  11. Enter your partially signed TXN
  12. Verify the Status reads "Partially signed (2/3)"
  13. In the Preview screen hit "Sign", then "Broadcast"

Conclusion

Certainly more complicated than a non MS wallet, but a lot more secure. Also be aware that the Segwit MS TXNs are about 40% larger than the native Segwit TXNs, so this does generate some additional cost in TXN fees.

does the “cold device” in these cold storage mechanisms essentially just hold your private key and your latest known balance?
No. Tails forgets all data upon reboot. You have to have a papemetal/brain-backup of the seed.
You import the master-PUBLIC-key into an online system, for example Electrum running on your Android phone or tablet. That system knows your balance, because it is online and can derive all addresses from the master-public-key. But it can't sign any transaction, because it doesn't have the seed.
If you want to spend, you create an unsigned transaction on the online-installation, transfer it to the offline system, check it, sign it, double check it, transfer the signed transaction to the online system and then broadcast it from there. Sounds more complicated than it is. Works really good with QR-codes.
Here are some old videos explaining the process. The software has changed slightly in the meantime, but the process should be made clear form watching that. The first video is now actually redundant, because Tails exists and you don't have to create your own Linux live system that has Electrum.

help ungoogling my phone

Hello there, I've been in the process of ungoogling an smartphone, here's what I've done so far:
- LineageOS as my OS (pure LineageOS without MicroG)
- I use F-DROID instead of GAPPS, Bromite instead of Chrome, NewPipe instead of YouTube, Tutanota instead of Gmail, OsmAnd instead of Google Maps and Aegis instead of Google Authenticator
- The only other apps I have on my phone are RedReader (for Reddit), Twidere (for Twitter), Telegram, WhatsApp (sadly you need to have WhatsApp in my country, some people told me to use an app called Shelter to isolate WhatsApp, what do you think?), Joplin (for notes), Electrum (bitcoin wallet), and my VPN's android app.
So, what do you think I should add or it's missing? I was recommended to install a firewall like NetGuard or Afwall, however, I was told that you can either use or VPN or a firewall like NetGuard, but, if you're rooted you can use Afwall and a VPN, I've read about rooting my smartphone but, I don't know why it seems very risky for a beginner like me (I read that you can brick your phone if you don't do things correctly, dunno if this claim is true tho). Would you recommend me to root my phone?

How to make a mobile wallet connect to my full node through Electrum Personal Server?

I have Bitcoin Core (full sync) and Electum personal server with basic configuration in linux (mint) but I don't have enough technical knowledge on how to connect to mobille wallets like bluewallet, samourai, breadwallet (BRD), coinomi etc, all of them unfortunately require that connect to an electrum server instead of our own node (direct enter IP address).
But unfortunately I can't find any tutorial on the internet, could someone please tell me what to do?
Detail: Some wallets like Bitcoin wallet for android (schildbacth wallet) and BRD allow you to connect to your full node just by adding your IP address (which would be much easier and more convenient), however my node is configured with tor and these apps do not add address .onion.
Is it possible to do this only using the electrum personal server or EPS only connects locally and does not allow more than one connection?
Do I have to install another electrum server like ElectrumX?
Do I need to create an alias certificate to connect to these mobile wallets?
Motivation: Why the need to connect these mobille wallet apps to my own node since these apps automatically connect to their own servers, and obviously will require a lot of technical knowledge in addition to time?? Because I care a lot about my privacy and I believe that most users that run full node not only to help the network, but to validate and transmit their own transactions instead of relying on third parties for this function. One of my motivations is also because I have a full node and I want to live up to the almost 300gb that occupy my HDD, I have already managed to make my Electrum wallet to connect to my full node through EPS, now my goal is to connect mobille wallets with my own node that have this option. 
Thankful.

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

New wallet set up, is this good?

"Also posted in /Bitcoin but haven't got any responses"
At the moment I am using the blockstream green wallet, which I really like, interface wise etc. but I want more security. I will keep this wallet as a spending wallet with small amounts and have most of the Satoshi's transferred to a "hodl for life wallet". I want to set up an electrum wallet in Ubuntu while offline and delete it afterwards, only keeping the seed phrase. On my android smartphone I will set up a Watch-only electrum to keep track of it.
So here's the plan:
Receiving funds should be easy, just send an amount to a public adress and I can verify it on the app.(will test a small amount)
Sending funds (which will happen rarely), but I will test with a small amount:
Is this gonna work? Any tips, suggestions?
There are probably more secure/advanced ways to do something like this. But although I've used linux/Ubuntu years ago, I'm still a beginner. And regards bitcoin/blockchain just started out getting in depth about a month ago and the more I get to know about it, the more I realise what a legend Satoshi is.
Edit: Another side question, if anyone finds out your seed phrase and gets access to your wallet, but won't transfer any funds, will you find out somebody had access?
Cause I just tried it with green wallet, I installed the app on another phone, used my seed phrase and entered my account. I could still access with my own phone and wouldn't have known somebody has been in my wallet?

Day 2: I will repost this guide daily until available solutions like Segwit & order batching are adopted, the mempool is empty once again, and transaction fees are low. You can help. Take action today

Subhan Nadeem has pointed out that:
If every transaction in the Bitcoin network was a SegWit transaction today, blocks would contain up to 8,000 transactions, and the 138,000 unconfirmed transaction backlog would disappear instantly. Transaction fees would be almost non-existent once again.
A few thousand bitcoin users from /Bitcoin switching to making their next transactions Segwit transactions will help take pressure off the network now, and together we can encourage exchanges/wallets to rapidly deploy Segwit for everyone ASAP. Let's make it happen.
Exchanges: Find out if your exchange has deployed Segwit already. If not, politely request that they do so within 30-days or they will lose your business. Sign-up for an account with a Segwit deployed/ready exchange now

  • No, just get ready now so that your NEXT transaction will be to a Segwit wallet.
Can you please tell me how to move my bitcoins to segwit address in Bitcoin core wallet? Does the sender or receiver matter?
  • The Bitcoin core wallet does not yet have a GUI for its Segwit functionality. Download Electrum v3.0.3 to generate a Segwit address.
    via HowToToken.com:
    A transaction between two SegWit addresses is a SegWit transaction.
    A transaction sent from a SegWit address to a non-SegWit address is a SegWit transaction.
    A transaction sent from a non-SegWit address to a SegWit address is NOT a SegWit transaction. You can send a Segwit Tx if the sending address is a Segwit address.
Is there a hardware wallet that does segwit addresses?
  • Yes, Trezor supports Segwit by default. Ledger Nano also has support.
What wallet are you using to "batch your sends"? And how can I do that?
  • Using Electrum, the "Tools" menu option: "Pay to many".
    Just enter your receive addresses and the amounts for each, and you can send multiple transactions for nearly the price of one.

Day 4: I will repost this guide daily until available solutions like SegWit & order batching are mass adopted, the mempool is empty once again, and transaction fees are low. ARE YOU PART OF THE SOLUTION? News: Unconfirmed TX's @ 174K, more exchanges adding SegWit, Core prioritizes SegWit GUI

NOTE Just a daily repost because original OP Bastiat seems to be offline (due to holidays I guess). However, this is quite important as I see much misinformation on which exchanges use segwit or not. Please upvote for awareness.
BACKGROUND
Subhan Nadeem has pointed out that:
If every transaction in the Bitcoin network was a SegWit transaction today, blocks would contain up to 8,000 transactions, and the 138,000 unconfirmed transaction backlog would disappear instantly. Transaction fees would be almost non-existent once again.
A few thousand bitcoin users from /Bitcoin switching to making their next transactions SegWit transactions will help take pressure off the network now, and together we can encourage exchanges/wallets to rapidly deploy SegWit for everyone ASAP. Let's make it happen. You can help by taking one or more of the action steps below.
ACTION STEPS
  1. If your favorite wallet has not yet implemented SegWit, kindly ask them to do so immediately. In the meantime start using a wallet that has already implemented SegWit.
  2. If your favorite exchange has not yet implemented SegWit, try to avoid making any further purchases of bitcoin at that exchange and politely inform them that if they do not enable SegWit within 30-days they will lose your business. Sign-up for an account at a SegWit deployed exchange now and initiate the verification process so you'll be ready to bail
  3. Help educate newcomers to bitcoin about the transaction issue, steer them towards SegWit wallets from day one, and encourage them to avoid ever purchasing bitcoin through non-SegWit ready exchanges that are harming bitcoin
IMPORTANT NOTE: The mempool is currently overflowing. If you are a long-term holder and really have no reason to move your bitcoins at this time, wait until the mempool starts to clear and transaction fees go down before moving your bitcoins to a SegWit address or SegWit friendly exchange
SELECTED TOP EXCHANGES BY SEGWIT & BATCHING STATUS
There are 2 different Segwit address formats.
  • p2sh - starting with a "3..."
  • bech32 - starting "bc1..."
Not many wallets/exchanges support bech32 yet and will claim the address is invalid if you try to send to it. bech32 ("native Segwit") is a mildly better solution compared to p2sh.

Please Teach me how to securely own my Bitcoin instead of keeping it on an online wallet.

I just recently purchased my first bits after Circle opened up to the public and made it so easy i had to try it. now that i actually own some bits I want to learn how to setup my wallet and create a number of backups that sync through Mega, Google Drive, and SyncThing now Ind.ie if i can learn how to set it up.
Please inform me on the most nooby friendly ways of getting this running (i have a android phone too that would be nice to set up).

Tutorial: How to receive Bitcoin donations on your Street Art works. This tutorial explains in 3 steps how to receive Bitcoin donations on your street art works:

Tutorial: How to receive Bitcoin donations on your Street Art works. This tutorial explains in 3 steps how to receive Bitcoin donations on your street art works:


Step 1 — Creating a Bitcoin Portfolio
First, it is necessary to create your wallet , which will generate your reception address (the equivalent of a bank account that belongs to you).
Thanks to this receiving address, you will be able to receive transactions in your wallet.
The Coinomiwallet is one of the easiest to use , available on Android, iOS, Windows, MacOS and Linux.
You are free to use any other wallet: Samurai Wallet , Spot , Electrum … Make sure that the wallet you choose is recognized and trusted because hacks , phishing and scams are commonplace in the world cryptocurrencies.
Download the application .

Once installed, click on “Create new wallet”.

The wallet will generate you your recovery phrase (or “Seed”, which is the private key of your wallet) which is most often a suite of 24 words.

Write down your recovery phrase by hand on a sheet of paper and keep it in a safe place (be careful to keep it private, anyone who owns this sentence becomes the owner of your funds).


Confirm to the wallet that you have correctly noted the recovery phrase and choose a password .
2nd step — Create your QR code visual
From your wallet, you need to generate your QR code of the receiving address .
Go to “Bitcoin BTC” in the wallet.

Click “Receive” (if indicated, choose a reception address “Compatibility” rather than “Default” or “Legacy”).


Bitcoin receive address example1F4bwjr74bmcXwRu53Jh27JRRCWHHd4yrz
You can now retrieve the QR code with a screenshot and save the receiving address .
To put this QR code on your works, there are 2 methods; a very simple and accessible to all (printing on paper and collage) and the second is a little more complicated (cutting stencil) but more durable:
  • The easiest way is to print the QR code on paper with the mention “Bitcoin donations” at the top and your Bitcoin receipt address at the bottom and paste it into your work.

Download this template and add your QR code and receiving address (as above). Check that the address shown corresponds to the QR code by scanning it with a smartphone.
Optional: It is recommended to add your website (or social networks) to allow people to validate that this is your Bitcoin address (and not that of a person posing as you). Of course, this same Bitcoin receiving address must appear on the front page of your site (and in your social networks profile) to allow donors to verify that the funds will be received by you.
Once the sheet is printed, you can paste it on your next street artwork. Prefer flat and smooth surfaces for better adhesion of the poster. We must make sure that it fits in with the signature of the work so that we understand that the gifts are for you.


- The second method is to create a QR code stencil and use a spray bomb to put it in your work.
There are 2 possible cutting techniques: A manual technique that requires some basic DIY. The second technique is to prepare the visual Photoshop and Illustator then to call a provider who will cut the stencil for you.
1st technique — Manual: To make yourself the stencil, you will need a rigid sheet, a cutting support, a cutting scalpel, Masking Tape, a black felt pen, a clamp and a thin square grid.
To make the QR code stencil by hand, see this tutorial .


Once the stencil of QR code is made, make a stencil with the mention “Donate Bitcoin” and add it to the first stencil to understand that this is your Bitcoin reception address. You can write it yourself or use this template (below) that you can print and overlay your rigid sheet.


Once your stencil is ready (“Donate Bitcoin” + QR code), you can put it on your next work with a black paint spray. Prefer flat, smooth and clear surfaces for a better readability of the QR code. We must make sure that the stencil is integrated into the signature of the work to understand that the gifts are for you.
2nd technique — Stencil cutting by a provider: To create a QR code stencil, it is imperative that all the background of the visual is connected to allow cutting of the stencil, for this, it is necessary to go to a site that generates QR compatible stencil code like qrcode-zebra.com


Once on the site, choose the “Text” tab and paste your Bitcoin receipt address and click on “Generate QR code”. Your QR code will appear, but the design will not be the right one. There are a few changes to make. In the “Choose patterns” tab on the left, click on the first pattern (which looks like a square grid), then in “Choose eyes”, click on the first box (the basic square “eyes”). Then, in “Set colors”, choose the color black.
Optional: if you wish to add your logo or signature, you can add it in “Add logo”. The file should be as simple as possible, in black with transparent background that connects (compatible with a stencil cut).
Now that the QR code is ready, you can retrieve it with a screenshot or click on “Dowload PNG” and give your email address to receive the QR code as a PNG file.
Then, on Photoshop, it is necessary to couple the grid of your QR code with this model so that the mention “Donations in Bitcoin” and the 3 “Eyes” square of the QR are compatible for a stencil cut. Use overlapping layers and erase old “eyes”.


Finally, download this special stencil typography and use it to enter your Bitcoin receipt address used on your QR code. Check that the address shown corresponds to the QR code by scanning it with a smartphone.
It is strongly recommended to also add your website (or social networks) to allow people to validate that this is your Bitcoin address (and not that of a person posing as you). Of course, this same Bitcoin receiving address must appear on the front page of your site (and in your social networks profile) to allow donors to verify that the funds will be received by you.
Once the visual is ready and fully compatible for stencil cutting, you can vectorize it in Illustrator and save it in EPS or AI format.
Last step, send this file to a provider who makes stencil cutting.
It’s up to you to choose the provider that best suits your location, price and time. Choose a format that suits your job. For large frescoes, larger formats (A2) are preferable, and for smaller works, smaller sizes (A4).

Once you receive the stencil, you can affix it to your next work with a black paint spray. Prefer flat, smooth and clear surfaces for a better readability of the QR code. We must make sure that it fits in with the signature of the work so that we understand that the gifts are for you.


3 — Last step, communicate.
Let all those who follow your work know that they can now support you financially by sending you Bitcoin donations on your Street Art works. You can use the means you have available, your contacts, your website, your social networks …
To help beginners, here is a tutorial that explains how to buy Bitcoin.
To track the transactions you receive, you can open your wallet regularly to see your balance.
To receive a notification when you receive a donation, you can use your Wallet to track transactions at an address of your choice.
The public can also see your balance received on your address thanks to blockchain explorers.
Here is the balance of a donation address: 3Pboy9ucGEdQUHNu2rrC6RGq4jouRc4Grb
If you receive a lot of donations, it is a good opportunity to communicate on the amount received.
Good luck and good creation!
FAQ
Why use Bitcoin?
The money you receive is 100% in your possession because you are the sole owner of your private key (recovery phrase, or “Seed”), unlike other centralized means of payment (Banks, Paypal, Ulule, Patreon. ..), Bitcoin happens totally of intermediary of confidence.
How do I use Bitcoin?
Thanks to your wallet you create a private key and a public address. The private key (recovery phrase, or “Seed”) is a bit like the key to your digital vault that you need to keep only for yourself. The public address is your RIB to receive transactions, you can share it publicly without problem.
How do I exchange my bitcoins for USD?
You can at any time send your bitcoins on an exchange online ( Coinbase …) to convert them into currency (Euro, Dollar …). You need to create an account on one of these exchange exchanges, convert your funds into the desired currency and then make a transfer to your bank account.
A faster solution may be to use a centralized service provider that offers a Bitcoin wallet connected to a credit card to spend your bitcoins directly ( Wirex , Coinbase …).

Bitcoin Rhodium Mining Guide

Bitcoin Rhodium Mining Guide
Happy Mining!

All available XRC pools can be found on MiningPoolStats

Bitcoin Rhodium Mining Hardware

Baikal Giant+: 1.6 GH/s
Baikal Quad Cube: 1.2 GH/s
Baikal Giant: 900 MH/s
Baikal Quadruple Mini Miner: 600 MH/s
Baikal Miner Cube: 300 MH/s
Baikal Mini Miner: 150 MH/s

Mining Setup

To mine Bitcoin Rhodium you need to set up an XRC wallet and configure your miner of choice. You can choose between Web wallet, Electrum-XRC or Magnum wallet. To set up a web wallet please visit wallet.bitcoinrh.org. Or download and install Electrum-XRC wallet (recommended) for Windows, Linux and MacOS.
Web wallet: wallet.bitcoinrh.org
Electrum-XRC wallet: electrum.bitcoinrh.org
Magnum wallet: https://magnumwallet.co

Sign up for XRC web wallet if not yet done so

  1. Create an account, with your username, password and secure question.
  2. Sign in and click “Create Wallet”.
  3. Set up a strong transaction password. Make sure you store it securely in a secure password manager of choice.
  4. Copy the seed somewhere safe. It’d be a good idea to write seed on a hardcopy and keep it safe.
  5. Paste it to confirm you got it right.
  6. Grab an address for the mining step. Your wallet is now ready to mine XRC.

Instructions for mining XRC on the official pool

Pool link: poolcore.bitcoinrh.org
  1. Any miner that supports X13 will be able to mine XRC. We have a few examples below of miners that are well tested with Bitcoin Rhodium network.
  2. For any miner, configure the miner to point to:
(0–0.8 GH/s) stratum+tcp://poolcore.bitcoinrh.org:3061
(0.8–2 GH/s) stratum+tcp://poolcore.bitcoinrh.org:3062
(3–4 GH/s) stratum+tcp://poolcore.bitcoinrh.org:3063
(5+ GH/s) stratum+tcp://poolcore.bitcoinrh.org:3064
with your XRC address as username and x as password. You don’t need to open an account on pool. You will be mining to XRC address and mined coins will be transferred to your wallet
after blocks reach 10 block maturity
after you mined up minimal amount of coins (currently 0.1 XRC)
sometimes mined blocks could get rejected by network (orphaned) after they were counted as valid blocks. This is normal network behavior to follow longest chain
  1. http://poolcore.bitcoinrh.org is used to follow your miner and network statistics.

CPU Miner-Multi

Source: https://github.com/tpruvot/cpuminer-multi

(3–4 GH/s) stratum+tcp://poolcore.bitcoinrh.org:3063
(5+ GH/s) stratum+tcp://poolcore.bitcoinrh.org:3064
Algo: x13User: your XRC receiving address (make sure you set 2 distinct addresses for each hashing board)
Pass: x
Extranonce: leave off Priority set to 0 and 1
Once pool stratum address and your wallet as user are set up you should see your miner mining against XRC pool. When miner is working the status column is green. The pool and miner are incorrectly configured now as status says “Dead” highlighted in red.

Instructions for mining XRC on BSOD pool

Pool link: bsod.pw/en/pool/dashboard/XRC/
Use this code for your miner: -a x13 -o stratum+tcp://pool.bsod.pw:2582 -u WALLET.rig
BSOD pool allows both solo and party mining.
For solo mining use code: -a x13 -o stratum+tcp://pool.bsod.pw:2582 -u WALLET.rig -p m=solo And for party mining use: -a x13 -o stratum+tcp://pool.bsod.pw:2582 -u WALLET.rig -p m=party.yourpassword
NOTICE: You can use us for North America and asia for Asia instead of euin your .bat file or config.
You can also use BSOD pool’s monitor app for Android and iOS.

Instructions for mining XRC on ZERGPOOL

Zergpool offers low fees (just 0.5%) and also SOLO and PARTY mining with no extra fees.
To mine XRC on Zergpool use this command lines for your miner:
Regular: -a x13 -o stratum+tcp://x13.mine.zergpool.com:3633 -u -p c=XRC,mc=XRC Solo: -a x13 -o stratum+tcp://x13.mine.zergpool.com:3633 -u -p c=XRC,mc=XRC,m=solo Party: -a x13 -o stratum+tcp://x13.mine.zergpool.com:3633 -u -p c=XRC,mc=XRC,m=party
Use your coin wallet address as username in mining software. Specify c=SYMBOL as password to identify payout wallet coin, and the same coin in mc=SYMBOL to specify mining coin.
For more information and support please visit http://zergpool.com
Notice that when there are more pools mining XRC in different geographic/availability locations choose the nearest to you as lowest priority and then add desirable fall back pool options in different geographic locations or pools. This is useful when one pool experiences issues, to fall back to different pool in Bitcoin Rhodium network.

Day 5: I will post this guide regularly until available solutions like SegWit & order batching are mass adopted, the mempool is empty once again, and transaction fees are low. User demand from this community can help lead to some big changes. Have you joined the /r/Bitcoin SegWit effort?

SUMMARY
Segregrated Witness (SegWit) was activated on the Bitcoin network August 24, 2017 as a soft fork that is backward compatible with previous bitcoin transactions (Understanding Segregated Witness). Since that time wallets and exchanges have been slow to deploy SegWit, some admitting in December 2017 that they have not even started work. If users demand SegWit now it will temporarily releive the transaction backlog while bigger solutions like Lightning are developed.

A few thousand bitcoin users from /Bitcoin switching to making their next transactions SegWit transactions will help take pressure off the network now, and together we can encourage exchanges/wallets to rapidly deploy SegWit for everyone ASAP.

  4. Spread the word! Conact individuals, websites, etc that use bitcoin, explain the benefits of SegWit to everyone, and request they make the switch
IMPORTANT NOTE: The mempool is currently still quite backlogged. If you are a long-term holder and really have no reason to move your bitcoins at this time, wait until the mempool starts to clear and transaction fees go down before moving your bitcoins to a SegWit address or SegWit friendly exchange.

If I'm a HODLer, will it help to send my BTC to a SegWit address now?
  • No, just get ready now so that your NEXT transaction will be to a SegWit wallet. Avoid burdening the network with any unneccessary transactions for now.
Can you please tell me how to move my bitcoins to SegWit address in Bitcoin core wallet? Does the sender or receiver matter?
  • The Bitcoin core wallet does not yet have a GUI for its SegWit functionality. Download Electrum v3.0.3 to generate a SegWit address.
    A transaction between two SegWit addresses is a SegWit transaction.
    A transaction sent from a SegWit address to a non-SegWit address is a SegWit transaction.
    A transaction sent from a non-SegWit address to a SegWit address is NOT a SegWit transaction. You can send a SegWit Tx if the sending address is a SegWit address.

My first experience using Lightning Network

I figured it was time to see for myself just how easy or difficult it was to use LN, and no better opportunity than to troll satoshis.place with some memes. I figured if there was a light wallet (Eclair) for android, there'd be something similar for Windows or even Linux to patch through Electrum. Well, after some research, there isn't, at least that I can find. If you want to use LN on desktop, you need a full client which means you need a full Bitcoin Core node.
And apparently, if you want LN to work somewhat decently at all, you need a full client, because out of 100 or more tries to push to satoshis.place payment requests on Eclair for android, only a handful succeeded, as connection to the channel is constantly dropping off an on multiple times a minute, even with a channel opened directly to them.
So I thought I'd try the other mobile LN wallet "Bitcoin Lightning Wallet". After funding it and opening a channel with a large hub, I thought I'd be able to route straight to satoshis.place. Unfortunately no, it appears you have to open a channel directly with who you want to transact with on this one as well, and it won't even let me open a channel with SP because "Data loss protection is not provided by this peer".
Needless to say, it's pretty ridiculous in order just to have some fun on this stupid website, I'd have to spin up a Linux box, install a full Bitcoin Core wallet (yay, let me sync for a few days), then install a full LN Daemon on top if it which I'll need to keep online for as long as I have a channel open.
The user experience is no where near at the point of SPV Bitcoin wallets, it barely works at all on the "easy methods".

Day 9: I will post this guide regularly until available solutions like SegWit, order batching, and Lightning payment channels are mass adopted, the mempool is empty once again, and tx fees are low. Have you done your part?

BACKGROUND
Segregated Witness (SegWit) was activated on the Bitcoin network August 24 2017 as a soft fork that is backward compatible with previous bitcoin transactions (Understanding Segregated Witness). Since that time wallets and exchanges have been slow to deploy SegWit, and the majority of users have not made the switch themselves.
On Dec 18 2017 Subhan Nadeem has pointed out that: If every transaction in the Bitcoin network was a SegWit transaction today, blocks would contain up to 8,000 transactions, and the 138,000 unconfirmed transaction backlog would disappear instantly. Transaction fees would be almost non-existent once again.
Mass SegWit use alone could empty the mempool, result in blocks that are not completely full, and make it possible to include transactions with $0 fee once again.
On Jan 11 2018 when BTC sends went offline at Coinbase the mempool began to rapidly empty. Later in the day when service was restored there was a sharp spike up in the mempool. Subsequently, that afternoon Brian Armstrong finally had to break his silence on the topic and admitted Coinbase is working on SegWit but has still not deployed it. It appears that this is an important data point that indicates if just a few major exchanges would deploy SegWit the high fees bitcoin is experiencing would be eliminated.
SegWit is just one technique available to exchanges and users to reduce pressure on the Bitcoin network. You can make the switch to SegWit on your next transaction, and pressure exchanges to deploy SegWit NOW along with other actions that will reduce their transaction impact on the network. You can help by taking one or more of the action steps below.
ACTION STEPS
  1. If your favorite wallet has not yet implemented SegWit, kindly ask them to do so immediately. If your wallet is not committed to implementing SegWit fast, speak out online any way you can and turn up the pressure. In the meantime start using a wallet that has already implemented SegWit.
  2. If your favorite exchange has not yet implemented SegWit, try to avoid making any further purchases of bitcoin at that exchange and politely inform them that if they do not enable SegWit within 30-days they will lose your business. Sign-up for an account at a SegWit deployed/ready exchange now and initiate the verification process so you'll be ready to bail
  3. Help educate newcomers to bitcoin about the transaction issue, steer them towards SegWit wallets from day one, and encourage them to avoid ever purchasing bitcoin through non-SegWit ready exchanges that are harming bitcoin.
  4. Spread the word! Contact individuals, websites, etc that use bitcoin, explain the benefits of SegWit to everyone, and request they make the switch. Use social media to point out the benefits of SegWit adoption.
IMPORTANT NOTE: The mempool is currently still quite backlogged. If you are a long-term holder and really have no reason to move your bitcoins at this time, wait until the mempool starts to clear and transaction fees go down before moving your bitcoins to a SegWit address or SegWit friendly exchange.
BEYOND SEGWIT - BATCHING, PAYMENT CHANNELS, LIGHTNING
Batching is another great way that exchanges can reduce their fees. See: Saving up to 80% on Bitcoin transaction fees by batching payments. Despite the benefits of batching, some exchanges have been slow to implement it. Users should demand this or walk.
Beyond SegWit & Batching, Lightning Network integration will have even more effect. Lightning is now active and exchanges could setup payment channels between each other so that on-chain transactions need not take place. Some ideas have to outline how that might work are here: Google Doc - Lightning Exchanges. Which two bitcoin exchanges will be the first to establish a lightning channel between themselves and offer free/instant transfers between them for their customers? This will happen in 2018

FAQs
If I'm a HODLer, will it help to send my BTC to a SegWit address now?
No, just get ready now so that your NEXT transaction will be to a SegWit wallet. Avoid burdening the network with any unnecessary transactions for now.
Why is SegWit adoption going so slowly? Is it a time-consuming process, is there risk involved, is it laziness, or something else?
SegWit will require some extra work to be done right and securely. Also, most exchanges let the user pay the fee, and up to now users have not been overly concerned about fees so for some exchanges it hasn't been a priority.
Once Segwit is FULLY adopted, what do we see the fees/transaction times going to?
Times stay the same - fees will go down. How much and for how long depends on what the demand for transactions will be at that time.
What determines bitcoin transaction fees, to begin with?
Fees are charged per byte of data and are bid up by users. Miners will typically include the transaction with the highest fee/byte first.
Can you please tell me how to move my bitcoins to SegWit address in Bitcoin core wallet? Does the sender or receiver matter?
The Bitcoin core wallet does not yet have a GUI for its SegWit functionality. Download the latest version of Electrum to generate a SegWit address.
A transaction between two SegWit addresses is a SegWit transaction.
A transaction sent from a SegWit address to a non-SegWit address is a SegWit transaction.
A transaction sent from a non-SegWit address to a SegWit address is NOT a SegWit transaction. You can send a SegWit Tx if the sending address is a SegWit address.
Source: HowToToken
What wallet are you using to "batch your sends"? And how can I do that?
Using Electrum, the "Tools" menu option: "Pay to many".
Just enter your receive addresses and the amounts for each, and you can send multiple transactions for nearly the price of one.
Why doesn't the Core Wallet yet support SegWit?
The Core Wallet supports SegWit, but its GUI doesn't. The next update will likely have GUI support built-in
Why isn't a large exchange like Coinbase SegWit ready & deployed when much smaller exchanges already are? Why do they default to high fees? Where is the leadership there?
Draw your own conclusions based on their own words:
March 2016 - Coinbase CEO Brian Armstrong has reservations about Core
Dec 2017 - Coinbase is STILL working on Segwit
P2SH/bech32 FAQs
What are the two SegWit address formats and why do they exist?
It's been a challenge for wallet developers to implement SegWit in a way that users can easily and without too much disruption migrate from legacy to SegWit addresses. The first wallets to enable SegWit addresses – Ledger, Trezor, Core, GreenAddress – use so-called “nested P2SH addresses.” This means they take the existing Pay 2 Script Hash address – starting with a “3” – and put a SegWit address into it. This enables a high grade of compatibility to exist wallets as every wallet is familiar with these addresses, but it is a workaround which results in SegWit transactions needing around 10 percent more space than they otherwise would.
Electrum 3.0 was the first wallet to use bech32 addresses instead of nested p2sh addresses.
Source: BTCManager.com
What is the difference in address format between SegWit address formats P2SH and bech32?
P2SH starts with "3..."
bech32 starts with "bc1..."
Which addresses can I send from/to?
P2SH Segwit addresses can be sent to using older Bitcoin software with no Segwit support. This supports backward compatibility
bech32 can only be sent to from newer Bitcoin software that support bech32. Ex: Electrum
Source: BitcoinTalk.org
Why did ThePirateBay put up two Bitcoin donation addresses on their frontpage, one bech32 and one not?
The address starting with a "3..." is a P2SH SegWit address that can be sent BTC from any bitcoin address including a legacy address. The address starting with a "bc1..." is a bech32 SegWit address that can only be sent to from newer wallets that support bech32.

A tutorial for Tails linux, to stay safe on Internet.

I'm not so sure this will be a help or not, quite sure that official guide is more reliable than this. anyway that's what I have here. If this article contains any kinds of misleading or error, please let me know in the comments.
A tutorial for tails linux, to stay safe on the Internet.
In today's circumstances, it's good to put more effort on maintain a low profile on Internet, or atleast learn how to do that.
If you already have a computer at home, you need to consider to use Tails linux if safety is what your concern about.
Access to https://tails.boum.org/ then follow download instructions.
The idea of tails is, it will anonymize your entire connection on Internet by using Tor network. So no one will discover your identity without lots of effort.
Not only that, once you do shutdown your device, it no longer holds any information. That means, other one can't find any evidence from your device.
Also if you still want to storage some text on tails, The easiest way is hide that in online email account.
At first, open text editor that preinstalled in tails. https://www.reddit.com/tails/comments/bm65w7/tails_faq_what_happened_to_the_pgp_clipboard_in/?utm_medium=android_app&utm_source=share
Then, follow the instruction to encrypt your text by passwords and paste it on email account through tor browser. Do not use that account to communicate to others, just keep it in secret. https://tails.boum.org/doc/encryption_and_privacy/gpgapplet/passphrase_encryption/index.en.html
If you are about to send messages through email, this instruction could be handy. https://tails.boum.org/doc/encryption_and_privacy/gpgapplet/public-key_cryptography/index.en.html You needs to learn about PGP first, tho.use XMPP is the either easier or safer plan.
You can encrypt other type of files by using Archive manager(give a right click on the file), but the computer gets freeze by that occasionally.
I strongly recommend to use Veracrypt hidden volume instead of build a Persistent storage feature, or LUCKS encrypted drive for linux that available on tails for both send/storage purposes.
In that way, you'll get two of passwords for one encrypted storage. If you are forced to reveal your password by others, you have a option to reveal a fake one.
On top of that, if you use another USB for that purpose, you don't have to slow down Tails itself. Persistent storage is tends to be fragile, I occasionally toast an entire data during excessive use. https://www.veracrypt.fen/Hidden%20Volume.html https://tails.boum.org/doc/encryption_and_privacy/veracrypt/index.en.html
You need to use other OSs for create new volumes. Linux is safer than windows I guess, but it takes an effort.
IIRC, you should check "I use hidden volume" radio button during type the password. Otherwise your hidden password doesn't simply work. Don't get confused by that.
Not only that, Tails has the Mac address spoofing function by default. Mac address is the unique identifier for your device. https://en.m.wikipedia.org/wiki/MAC_address
That function also increases anonymity on Internet. it's important when you go outside because even if you killed GPS function on your devices, it still leave a Mac address on wifi router or 3G/LTE cellular module nearby. So someone still can trace your location.
Also just in case if your government decides to not allow you to connect tor network, you should read this article first. https://tails.boum.org/doc/first_steps/startup_options/bridge_mode/index.en.html
But if every each of instruction seems failed to helps you, bring your device(with Mac address spoofing function) outside and connect to the Free wifi. https://freetoursbyfoot.com/where-find-free-wifi-london/
It's relatively safe since either of wifi or device doesn't leave the information that directly leads to you, but be aware on surveillance camera nearby. don't stay there too long, or use one spot too frequently.
I know laptops is too cumbersome to carry around, you have a option to choose something like a windows tablet, a stick pc along with touch screen or a Tv box. not sure on which kind of stuff do the best job unfortunately.
For communication, you need to build the safest/robust assembly point on Internet. The very best option available is XMPP Pidgin chat client.
It's pre-installed in the tails. https://tails.boum.org/doc/anonymous_internet/pidgin/index.en.html As you expected, you can start a group chat. https://superuser.com/questions/1440212/is-there-any-way-to-create-a-group-in-pidgin-like-in-whatsapp
There is couple things you can't do on Tor network or tails Linux.
First, you should read these articles. https://www.hongkiat.com/blog/do-donts-tor-network/amp/ https://tails.boum.org/doc/about/warning/index.en.html https://2019.www.torproject.org/docs/faq.html.en
Since tails is lots more robust than Tor browser bundle on windows, you can ignore the most of issues in Tor browser. Still you have to aware the risk on this.
Not only that, couple of things is getting harder to achieve through Tor.
At first, some website like Twitter, Reddit or YouTube tends to reject to create an account. If that was just a couple of exit nodes, maybe restart the browser might do the trick. https://tor.stackexchange.com/questions/19536/cant-use-reddit-on-tor-what-do-i-do
But if entire exit nodes are rejected by provider, Web based proxy gives you a chance. If that doesn't work, I'd say you should find someone who will to post your messages on viral media.
Secondly, even if you using tails, thats not means you can pay for something anonymously.
If you need to use paid Web base proxy or whatever you want, it's also safer to use anonymous cryptocurrency such as Zcash or monero. not sure how safe are they, pre-installed wallet(Electrum) only supports bitcoin. so you need to use web based wallets.
Or if someone donated a bitcoins to your anonymous wallet, it's safe to use that one through Tor.

Day 7: I will post this guide regularly until available solutions like SegWit & order batching are mass adopted, the mempool is empty once again, and tx fees are low. Do you want low tx fees, because this is how you get low tx fees

TL/DR
Bitcoin users can help lower transaction fees and improve bitcoin by switching to SegWit addresses and encourage wallets/exchanges to do the same.
SUMMARY
Segregated Witness (SegWit) was activated on the Bitcoin network August 24 2017 as a soft fork that is backward compatible with previous bitcoin transactions (Understanding Segregated Witness). Since that time wallets and exchanges have been slow to deploy SegWit, some admitting in December 2017 that they have not even started work on integrating it. Others, such as Zebpay in India have already implemented SegWit and are reaping the benefits of reduced transaction fees. If bitcoin users demand SegWit now it will temporarily relieve the transaction backlog while more even more advanced solutions such as Lightning are developed.
Batching is another great way that exchanges can reduce their fees. See: Saving up to 80% on Bitcoin transaction fees by batching payments. Despite the benefits of batching, some exchanges have been slow to implement it.
There is an opportunity now for all bitcoin users to individually contribute to help strengthen and improve the bitcoin protocol. At this point, the process requires a bit of work/learning on the part of the user, but in doing so you'll actually be advancing bitcoin and leaving what could turn out to be a multi-generational legacy for humanity.

Day 8: I will post this guide regularly until available solutions like SegWit, order batching, and Lightning payment channels are mass adopted, the mempool is empty once again, and tx fees are low. BTC Core SegWit GUI coming May 1, Coinbase incompetence exposed, more exchanges deploy SegWit

BACKGROUND
Segregated Witness (SegWit) was activated on the Bitcoin network August 24 2017 as a soft fork that is backward compatible with previous bitcoin transactions (Understanding Segregated Witness). Since that time wallets and exchanges have been slow to deploy SegWit, and the majority of users have not made the switch themselves.
On Dec 18 2017 Subhan Nadeem has pointed out that: If every transaction in the Bitcoin network was a SegWit transaction today, blocks would contain up to 8,000 transactions, and the 138,000 unconfirmed transaction backlog would disappear instantly. Transaction fees would be almost non-existent once again.
Mass SegWit use alone could empty the mempool, result in blocks that are not completely full, and make it possible to include transactions with $0 fee once again.
On Jan 11 2018 when BTC sends went offline at Coinbase the mempool began to rapidly empty. Later in the day when service was restored there was a sharp spike up in the mempool. Subsequently, that afternoon Brian Armstrong finally had to break his silence on the topic and admitted Coinbase is working on SegWit but has still not deployed it. It appears that the high fees bitcoin is experiencing could be easily addressed and need not exist.
SegWit is just one technique available to exchanges and users to reduce pressure on the Bitcoin network. You can make the switch to SegWit on your next transaction, and pressure exchanges to deploy SegWit NOW along with other actions that will reduce their transaction impact on the network. You can help by taking one or more of the action steps below.

Can you please tell me how to move my bitcoins to SegWit address in Bitcoin core wallet? Does the sender or receiver matter?
The Bitcoin core wallet does not yet have a GUI for its SegWit functionality. Download the latest version of Electrum to generate a SegWit address.
A transaction between two SegWit addresses is a SegWit transaction.
A transaction sent from a SegWit address to a non-SegWit address is a SegWit transaction.
A transaction sent from a non-SegWit address to a SegWit address is NOT a SegWit transaction. You can send a SegWit Tx if the sending address is a SegWit address.

What wallet are you using to "batch your sends"? And how can I do that?
Using Electrum, the "Tools" menu option: "Pay to many".
Just enter your receive addresses and the amounts for each, and you can send multiple transactions for nearly the price of one.
Why doesn't the Core Wallet yet support SegWit?
The Core Wallet supports SegWit, but its GUI doesn't. The next update will likely have GUI support built-in
Why isn't a large exchange like Coinbase SegWit ready & deployed when much smaller exchanges already are? Why do they default to high fees? Where is the leadership there?
Draw your own conclusions based on their own words:
March 2016 - Coinbase CEO Brian Armstrong has reservations about Core
Dec 2017 - Coinbase is STILL working on Segwit
P2SH/bech32 FAQs
What are the two SegWit address formats and why do they exist?
It's been a challenge for wallet developers to implement SegWit in a way that users can easily and without too much disruption migrate from legacy to SegWit addresses. The first wallets to enable SegWit addresses – Ledger, Trezor, Core, GreenAddress – use so-called “nested P2SH addresses.” This means they take the existing Pay 2 Script Hash address – starting with a “3” – and put a SegWit address into it. This enables a high grade of compatibility to exist wallets as every wallet is familiar with these addresses, but it is a workaround which results in SegWit transactions needing around 10 percent more space than they otherwise would.
Electrum 3.0 was the first wallet to use bech32 addresses instead of nested p2sh addresses.

What is the difference in address format between SegWit address formats P2SH and bech32?
P2SH starts with "3..."
bech32 starts with "bc1..."
Which addresses can I send from/to?
P2SH Segwit addresses can be sent to using older Bitcoin software with no Segwit support. This supports backward compatibility
bech32 can only be sent to from newer Bitcoin software that support bech32. Ex: Electrum

Why did ThePirateBay put up two Bitcoin donation addresses on their frontpage, one bech32 and one not?
The address starting with a "3..." is a P2SH SegWit address that can be sent BTC from any bitcoin address including a legacy address. The address starting with a "bc1..." is a bech32 SegWit address that can only be sent to from newer wallets that support bech32.
