Shouldn't all true crypto believers hate this news? It's the government trying to enforce their opinion of who should own those Bitcoins, thereby taking power away from the owner that the network has decided on, which would be "whoever has the cryptographic keys".

Bitcoin never claimed it was going to put a magical fence around your house stopping armed agents.

It seems that Tornado Cash ( https://tornado.cash/ ) could have been used to launder the funds. I wonder if: - Laundering happened before Tornado Cash existed, so Tornado Cash was not used - They used something like Tornado Cash, but the funds were still traceable

So, tornado only takes Eth. They could have used something like wbtc, to bridge the bitcoin to Ethereum and then swap to eth to run it through tornado. But wbtc is a custodial wrapping service that would require kyc. There are other wrapping services that don't, but they have nowhere near that much liquidity on Ethereum to execute the trade to eth needed to run it through tornado. The other problem is that tornado ha…

Good points! Thorchain (a non-custodial service) claims 1.9B total swap volume. So, while not viable today for billions of dollars, the Bitcoin -> Thorchain -> Tornado Cash pathway seems to be viable for smaller amounts. Which doesn't necessarily bode well for recovering stolen bitcoin (and other crypto) in the future.

A thief still has to figure out how to convert crypto to fiat. But I am assuming that there are jurisdictions where this is possible without KYC.

I agree. But if not for privacy, why use crypto at all? Even bank accounts are reasonably private, if you are not doing anything considered suspicious by society. Also, with mixers such as tornado_cash, laundering money is , sadly , pretty trivial.

Mixing is not laundering. The difference is that laundering provides you with an explanation for wealth and/or income. Example of laundering: buy a business (with clean or borrowed money), have fictional customers "spend" their cash money at your business every day, then report your income and pay taxes. Now if anybody asks about where you got your money, you have a seemingly legit explanation. Mixing does none of th…

tornado.cash puts your crypto in a completely fresh account (using smart contracts). You can claim that you earned this crypto mining it back in 2010. You can definitely come up with a decent excuse for this.

Then you can convert those crypto (in new account) into fiat money.

Everyone will know you are lying, but they will never be able to prove it.

> charged with conspiracy to commit money laundering, and conspiracy to defraud the United States

Do you think there are more charges to come?

If they think they actually laundered money through businesses, why didn't they charge them with multiple counts of money laundering and multiple counts of wire fraud and a violation of the CFAA?

vitalik (ethereum founder) used an interesting system. He split the key in 2. Wrote both on paper. Gave 1 paper to family and kept the other. Even if the police raid him (hypothetically), they cannot raid the houses of his family and friends at the same time This way the police or anybody else cannot get your private key.

No, but if you don't have your half memorized and they take it from you, the other half is useless. This is more useful if you want to leave your crypto to your family if you die, provided that you make it easy for them to find your half if you're not around.

Excellent point! I never considered this.

Should I expect price drop once feds start to sell it? Or they'll just destroy the keys (keeping the money invested forever).

I'd actually really like if they used this opportunity to drive the Bitcoin price straight into the ground, thereby ruining that market for all those speculative investors.

Maybe that'd allow for something of a reboot of the ecosystem having eliminated the scum that usually starts to invade any remotely financially exploitable system after a while.

fwiw, it appears one of the named here is a YC Alum: https://news.ycombinator.com/user?id=il https://www.linkedin.com/in/unrealdutch/

Should have just become a limited partner in one of the Silicon Valley PE funds, next to the Oligarchs

Well, yes. If you can socially engineer customer support staff, you can do the same to venture capitalists.

Then it seems pure luck that some conniving sociopath at the top can lead a company to produce useful goods.

That's extremely subjective to your definition of useful. Investing in the best con artist isn't exactly a bad deal so long as you aren't the last mark.

or you end up with a useless half key or your trusted accomplice helps in the investigation

The police don't know that you split the key. But I get what you mean. I am sure there are better ways to hide private keys.

Encrypting it with a good password that you remember and then printing the encrypted keys comes to mind.

They mention chain hopping and privacy chains. Maybe they slipped up using ZEC and made some of their transactions public?

where do mention?
