Trezor are now a malicious entity who fund mass surveillance and blockchain analysis and collude with the government to censor their users. I wouldn't buy one of their devices if it was 100% off.

Haha, perfect timing here as we discuss Passport:


And Trezor are hiding dozens and dozens of replies on Twitter calling them out for partnering with Wasabi and blockchain analysis. The irony of a pro-censorship company censoring everyone calling them out on their censorship. 

Trezor have really messed up big time here. No one should ever buy another Trezor device.

I can think of plenty of users with >500 merit who would quite happily abuse this and brigade another user's posts to have them all hidden, especially in the case of trust disputes. Also, such a feature would undoubtedly be misunderstood and used for posts the user dislikes or disagrees with, not just posts which are redundant.

Almost all wallets calculate the k value deterministically, so a transaction with identical inputs and outputs will almost always have the same signature.

In the rare case that someone used transaction malleability to change the TXID, then nodes would reject this new transaction since it does not meet the criteria for the increased fee as per BIP125. The original transaction would remain in the mempool.

And why would you want your hardware wallet to spy on you and sell you out for the sake of appeasing the government or their own reputation? The whole point of bitcoin is to not require permission from third parties in order to make the transactions you want, be they governments or blockchain analysis companies.

If I was going to buy a hardware wallet right now, I'd pick either a Passport or a Coldcard.

For your privacy.

Trezor is using Wasabi to perform their coinjoins, which pays blockchain analysis companies to spy on all your UTXOs and censor ones they don't like. I would stay well clear of this and all Trezor devices.

I don't think adding more AI generated text to the endless amount of spam will achieve anything. No one actually reads such replies anyway; they just get in the way of actual discussion. If we want to solve the spam problem, then we should just actually enforce the rules regarding spam and signature campaigns and start handing out temporary bans like the rules say we will.

Ahh, I see. I misunderstood your previous post - I thought you were saying you had already set up an Electrum server, when you were actually saying you already have Sparrow pointed at your own node. In that case, I would just use Sparrow for the use cases you described in your first post. It is more than capable of doing all of those, and you will maintain your privacy since it will only sync via your own node.

Whirlpool is a coinjoin implementation, run by Samourai, which is accessible via Sparrow. You can read more about it here: https://sparrowwallet.com/docs/mixing-whirlpool.html. Essentially, you pay a small fee and then coordinate with other users to create transactions which send the same amount of bitcoin you put in back to you, but in a way which obfuscates which bitcoin actually belong to you. If you are interested in anonymizing your bitcoin so entities such as centralized exchanges and blockchain analysis companies cannot trace it, then you could look in to this. If you do plan to use Whirlpool, make sure you also connect to the coordinator via Tor (explained in the link I just shared).

If you can do it properly, then I would argue that a properly airgapped cold wallet is better than a hardware wallet. The problem is it is much harder to do it properly and much easier to make a mistake than simply using a hardware wallet.

You will need a permanently airgapped computer. Ideally it should have all connectivity hardware such as WiFi, Bluetooth, etc., not just disabled but physically removed. You will need to format it and ideally write junk data to the entire hard drive to ensure there is nothing lurking on it you are unaware of. On a different computer, download and verify a good Linux distro and either Core or Electrum, and put these on a clean and recently formatted USB stick. Install Linux on your airgapped device, enable full disk encryption with a strong passphrase, and then install Core or Electrum and generate your wallet. Export an xpub via QR code to create a watch only wallet on your online computer, and use QR codes to move transactions back and forth. Use the airgapped computer for nothing else. Make sure you back up your wallet and your decryption passphrase, and do not rely on your memory for any of these backs ups.

So as you can see, it's a complex process if you don't really know what you are doing with many potential risks. If you are at all unsure, then a good hardware wallet such as a Passport paired with Electrum is probably a safer option.

No, it's no better or worse. In both cases, all your data will come from your own node rather than that of a third party, and so your privacy will be maintained. If you already have an Electrum server set up, then no reason not to use it.

If you are already familiar with Electrum and already have a server set up, then I see no reason to change unless you wanted to use Whirlpool.

Have your daughter generate 20 (for example) key pairs. She keeps the 20 private keys secret and gives you a list of 20 addresses.

Create a timelocked transaction sending 1 BTC to the first address, which cannot be broadcast for 1 year. Give her a copy of the transaction for safe keeping.
Create another timelocked transaction sending 1 BTC to the second address, which cannot be broadcast for 2 years. Again, give her a copy of the transaction.
Another transaction, timelocked for 3 years, to the third address. Give her a copy.
Etc.

If you die, then she can broadcast one transaction a year until she has broadcast them all.

If you are still alive in a year, then all you have to do is move the coins in the first transaction to a new address, and the timelocked transaction she is holding will be invalid and useless. So every year you are still alive, move the coins which she could redeem next to another address you own, and then create a new timelocked transaction for some other time in the future.

I would say the main benefit that Sparrow has over Electrum for your use case is how easy it so connect to your own node and not rely on a third party. Electrum requires that you set up an Electrum server on top of your node first; Sparrow can just be pointed directly at your node. Sparrow also allows you to Whirlpool directly from your wallet, as well as supporting other privacy improvements such as PayNyms and Stonewall transactions, but this is probably irrelevant if you are just going to use it as a watch only wallet.

I already answered you about this in another thread: https://bitcointalk.org/index.php?topic=5448892.msg62109874#msg62109874

The whole point of any hardware wallet is so that you cannot lose everything simply from having malware on your computer or clicking on a malicious link. Every transaction which is made sending coins out of your device needs to reviewed and confirmed on the device itself. If you authorize a malicious transaction because you didn't bother to check it properly, then there is nothing that any hardware device can do to stop that.

I don't see what this would achieve, or how you would do it. To send coins from an exchange to your hardware wallet, all you have to do is copy an address from your Ledger Live software and give it to the exchange, and then double/triple check the address is correct. There is nothing that a third party could to do help without showing up to your house and looking at your screen or you remotely sharing your screen with them, both of which would be a huge risk to your security and privacy. Anyone offering to help you do this via private messaging, Telegram, etc., is almost certainly going to try to scam you.

There is a difference between being named in an article and having your name connected directly to a Twitter account and a PayNym. Also this: https://nitter.it/SamouraiWallet/status/1647936591417995264

0.1% for makers if you pay in Bitcoin, 0.05% if you use BSQ.

Irrelevant. The individuals concerned do not want their identities shared. Previous mistakes in leaking private information do not give other people permission to share that information as widely as possible. If you had accidentally linked your forum name to your real life identity on some other site, you would be rightly very angry if I started plastering that information all over the forum.

As I said above, the landing page of wasabiwallet.io says "Privacy is your ability to selectively reveal yourself to the world". Sharing information about someone they do not wish to be shared violates this completely. It exposes Wasabi's complete hypocrisy and complete disregard for privacy.

Does such a thing exist? Any CEX will implement KYC in a heartbeat if failing to do so would affect their profits.

Bisq fees are 0.5%/0.05% for taker/maker. Coinbase fees for trades under $10k are 0.6%/0.4% for taker/maker. And then Coinbase will hit you with fiat/bitcoin withdrawal fees too.

Great job! Now the next task is to a figure out a second secure location to store your second back up. There is no point having two backs up if you store them in the same place (i.e. at home), since a single event such as a fire will wipe out both of them.

And there is absolutely no proof whatsoever that he actually lost those coins. Every claim of a lost wallet could simply be an unfortunate boating accident. I know I lose all my coins in an unfortunate boating accident frequently!

I do not doubt that some 10 year old dormant coins are indeed truly lost, but it is impossible to put even a ballpark estimate on it. CSW was so sure that a bunch of early dormant addresses from 2009 had been lost that he claimed they belonged to him in court, and then the true owner signed a message out of the blue calling him a fraud. And even if we say all these coins are truly lost, they will likely be recovered in the future as and when quantum computers are able to break the ECDLP, and so the number cannot be removed from the total available supply.

This is obviously the best option, and it's never been easier. We have the biggest choice of DEXs we've ever had, we have the most volume on DEXs that we've ever had, and we have the most advanced DEX (Bisq) that we've ever had.

Of course, but it actually doesn't matter who it is. Doxxing anyone simply because they disagree with you is utterly scumbag behavior.

How do you propose law enforcement take down JoinMarket, which is software which is run on thousands and thousands of individual computers around the world, via Tor, and has no central coordinator? How do you propose they take down Bisq, which has the same set up?

The truly decentralized services are resistant to censorship in exactly the same way bitcoin itself is. A government could shutdown a centralized exchange or Wasabi's centralized coordinator, but they can't shutdown every Bisq trader or every JoinMarket user, just as they can't shutdown every bitcoin node.

On another note, and I am deliberately not going to link to any of the tweets, but in the last 48 hours there has been a bunch of Twitter drama due to Wasabi publicly doxxing their competitors.

Says it all really. The landing page of wasabiwallet.io says in big font right at the start "Privacy is your ability to selectively reveal yourself to the world". And then the Wasabi devs completely ignore that statement and start doxxing people who disagree with them. Imagine trying to pass yourself off as pro-privacy as you fund blockchain analysis and dox people you don't like? Absolutely despicable behavior, and should show everyone just where the priorities of Wasabi lie. They don't care in the slightest about your privacy.

Can't wait for our resident shill to come and tell us how doxxing people you don't like is actually fine.

I posted about Kape and PIA a few years ago in this very thread: https://bitcointalk.org/index.php?topic=5372131.msg58547859#msg58547859
I just went back to check if that clause in their Privacy Policy about sharing your data still exists, and it does. In addition, I also found that they use BitPay to process bitcoin payments. The same BitPay renowned for requiring KYC from their customers and their terrible privacy practices. 

So yeah, I wouldn't go anywhere near PIA or anything else owned by Kape.
