In Bitcoin transactions are not just "from", "to" and "amount" even if some wallets abstract them in that way. In the simplest case there are coins that get marked as being spendable by some public key (address). That's the analogy with the password to a bank account was refering to. As long as you don't make use of that privilege then you can't be reasonably criminally convicted. That doesn't mean law enforcement wont come and ask questions. In Ethereum it is more like you said where a certain amount is actually credited to an address and at that point cannot be distinguished from other funds in that address. I agree both systems have enough information to handle the situation but again (I start to feel like a broken record) - there is a clear difference between them in that one needs active work to distance yourself from the funds while the other just requires not touching the tainted coins. You could also in Bitcoin go the extra step and actively burn those coins. Ideally the sanctioning body would provide an address of theirs where tainted coins can be sent and the sender then reimbursed for the fees or even awarded a small amount. Hopefully a judge would see when someone innocent received tainted funds but it would be a tad more difficult on Ethereum than on Bitcoin.
