If you are using lncli, then the command abandonchannel can be used to abandon a failed channel transaction, but I have no idea if it would work with a non-channel transaction. Make sure you know what you are doing with it though, since if you abandon an open channel then you'll probably lose all the coins in that channel.

The other option would be to restart lnd using the --reset-wallet-transactions command and force a rescan, as detailed here: https://github.com/lightningnetwork/lnd/blob/master/docs/recovery.md#forced-in-place-rescan. Again, if you have any open channels, make sure you have them backed up first.

No issues. Ledger devices use a BIP39 seed phrase, as do almost all current hardware and software wallets. You will have no trouble importing it elsewhere if you need to.

Just note that you should only do this in the situation where your hardware wallet is lost, damaged, broken, etc. Importing your seed phrase in to another wallet is risky, and has the potential to negate all the protection your hardware wallet provides.

No. Even if they take down Ledger the company, the coins on your hardware wallet will remain safe. And even if the Ledger servers all get taken offline and their software no longer works, you can pair your hardware wallet with many different pieces of wallet software, such as Electrum, in order to still access your coins. And if your physical hardware wallet is damaged, broken, lost, etc., then you can recover your bitcoin by recovering from your seed phrase.

I think you are confusing concepts here.

Binance is an exchange for trading bitcoin and fiat. A multi-sig set up is a type of wallet for holding bitcoins. A multi-sig wallet can not replicate an exchange, nor vice versa.

You don't need anyone to help you practice this. You can set up a multi-sig wallet on your own with three different Electrum wallets on the same device. Doing so removes much of the benefit of the multi-sig wallet (since all three wallets are on the same device, so the additional security gained over a single sig wallet is very minimal), but it is sufficient for testing purposes so you can learn how it works.

Yes.

Yes.

Your risk is lower if you use the device for nothing except bitcoin, but the risk can only be removed by keeping the device permanently offline. Since you are still using that device to browse social media, use search engines, and visit the random sites that the search engine returns, then your risk is barely reduced, if it all.

That's correct. If you want to enable full RBF on your node, then you just add mempoolfullrbf=1 to your bitcoin.conf file.

It is, but only to nodes that have enabled mempoolfullrbf as above, which are still in the minority. At some point it will be enabled by default, but it's not clear yet when that will happen.

At the moment, the only mining pool which we are certain is running full RBF on their nodes is Luxor, which have around 2-3% of the hashrate. So if you can get a replacement transaction broadcast through the nodes which are running full RBF and to one of Luxor's nodes, then you can technically currently replace any transaction.

If you are going to be buying a new computer for work and education anyway, then after you have your new one up and running you could use your current one for bitcoin only. Simply format it and get a clean install of your OS on it first.

If you would prefer to use a phone for this, then that's up to you. I wouldn't wait until you have 1 BTC on a centralized exchange before you transfer it out though. You can transfer it in smaller amounts incrementally to your Ledger. You'll pay a little more in fees, but it's worth it for not having to store your BTC long term on a centralized exchange while you wait to accumulate enough. Also less risk of losing everything if you make a mistake with one transfer if you are transferring smaller amounts repeatedly rather than all at once.

Correct. You'll need to hook up your Ledger to your computer when you first initialize it in order to download the latest firmware and the bitcoin app software, and you'll need to hook it up any time you want to spend coins from it. You don't have to connect it just to view the balance on your addresses, however.

Seems like the fee is the same:


I'd also be concerned about the fact you have to leave your Trezor plugged in and authorize it to automatically sign transactions which are passed to it. I'm sure that they've tested to make sure it only signs coinjoin transactions, but automatic signing still presents a whole new attack surface which does not exist on any existing hardware wallet as far as I am aware.

Not to be blunt, but so what? Anti-vaxxers parrot this all the time - "Well, they had a pre-existing condition!" - as if suffering from some chronic health condition means your life doesn't matter anymore.

Yes, the majority of the deaths were in the older population (although I really wouldn't class 50 as old), and yes, many (but certainly not all) of the younger people in ICU with COVID had pre-existing conditions. None of that made it any easier on their bereaved families or on the hospital staff.

Cool, so I can get blockchain analysis entities to specifically monitor the outputs in my hardware wallet now. Just what I've always wanted!

Plus Trezor being completely silent on the topic of Wasabi's blockchain analysis despite multiple questions about it on Twitter is not exactly good optics. Trying to take the Wasabi route of pretending the issue doesn't exist?

The suggestions above regarding having an airgapped device are good suggestions if you are planning to store your bitcoin on a wallet on that device. It sounds like you are not planning to do that, since you have bought a Ledger hardware wallet.

Given that your bitcoin will be safely stored on your Ledger, then having an airgapped computer doesn't really add anything to this set up. Correct me if I'm wrong, but it sounds like you will be using this computer to actually buy the bitcoin and send it to your hardware wallet? In that case, that computer cannot be airgapped - obviously it will need an internet connection in order to interact with an exchange or another person in order to purchase the bitcoin.

If that's the case then yes, it is good idea to have a clean computer which you only use for bitcoin and not for daily browsing or anything else, since this will minimize the risk of downloading malware. Personally, I would use a laptop, format it, and install a Linux distro of your choice on it rather than a closed source spyware OS like Windows. If you've never used Linux before, then a distro like Linux Mint is a good place to start.

Given how easy it is to enable RBF on a transaction, there really shouldn't ever be a reason to require a transaction accelerator anymore. Just opt in to RBF with every transaction you make, and you can replace it later with a higher fee if it gets stuck. This will work out much cheaper than paying any transaction accelerator service, not to mention quicker and easier as well. Even using CPFP will probably be much cheaper than paying for a transaction accelerator.

Is your transaction opted in to RBF, or does it produce a change output? If so, use RBF/CPFP instead.

I see you've still not grasped elementary school math. Keep trying, you'll get it eventually!

You can't.

Their definition of taint includes anything they want, and they won't tell you why:

For Android. On desktop you have a free text box and can set any fee you like. On Android there is just the slider, but a lot of people don't know you can tap to change the slider between three different categories.

Yeah, it's a real shame that Trezor have decided to support mass surveillance by partnering with a company which directly funds blockchain analysis, but Trezor have repeatedly shown they don't really have any respect for their users' privacy. Take, for example, them implementing KYC exchanges in to their software, or their support of AOPP last year.

Still, there are other hardware wallet manufacturers out there which are not pro-surveillance, so just buy from one of them instead.

We don't know that. Satoshi could reappear tomorrow and spend all their coins.

A prime example of this was several hundred early addresses which "woke up" after being dormant for 10 years in order to sign a message calling CSW a fraud.

This also doesn't mean that the coins are lost. People claim they have lost coins they haven't lost for a huge variety of reasons.

We agreed no such thing. You stated it because you have no better answer to Wasabi address reuse.

I see you are on Step 3 of our recurring conversation. Refers to my posts above for the evidence as per Step 1.

Keep it simple but safe. Use standard methods. Overcomplicating things is more likely to end up backfiring.

If it were me, I would be using a multi-sig set up using multiple separate airgapped devices. For example, three airgapped devices, each formatted with a fresh Linux install, full disk encryption, and Electrum. Use this to create a 2-of-3 multi-sig.

If you wanted to, you could substitute one or more of these devices for a good hardware wallet such as Passport, but be aware that sometimes the combination of hardware wallets and multi-sig can malfunction. You should test any set up thoroughly first.

Step 1 - Get shown blockchain evidence of Wasabi address reuse
Step 2 - Ignore said evidence
Step 3 - Ask for the evidence you've just ignored
Step 4 - Go to Step 1
