The Hermit Kingdom, which intelligence agencies say was behind the $1.5 billion Bybit hack, faces “offramping” challenges due to the size of its hauls.
Bitcoins aren’t really discrete individual units like that. Imagine you send me 0.1 bitcoin and my mom sends me 0.1 bitcoin and I then send 0.1 bitcoin to Alice (ignore transaction fees and such). It’s not really a meaningful question whether the sum Alice received was the fraction of a “coin” I received from you, from my mom or some specific mixture of both. The blockchain just records increases and decreases of a wallet’s balance.

Ish. If you received a million CSAM’n’heroin bucks, and you give 10 bucks to Alice, there’s a transaction history that now links Alice’s wallet to CSAM’n’heroin which can indeed be a problem for Alice, because cautious exchanges might now freeze her assets until she can offer some proof that she’s not doing anything bad.
There’s a bitcoin wallet attack that uses this trick that was mentioned recently, maybe here, maybe on web3igjg. You can argue the bitcoins aren’t the same, but in practise no-one cares.

eta: this is apparently called a “dust attack” and I first heard about it here: https://awful.systems/post/3463061
Merely interacting with a sanctioned wallet is enough to get or treated with suspicion, let alone receiving funds. Pecunia certainly olets these days.
