Bitcoin / Bitcoins / Crypto Currency

If you're referring to the fact that every transaction ever is visible on the blockchain, I expect that a fair number of people here are aware of it and it may have come up. That's not quite the same as traceable, though, since as long as you're personally managing your wallet/wallets, it's still anonymous; your wallets are anonymous, you can have as many as you want and each can be managing multiple addresses, so the fact that the transactions are visible doesn't make all your activity traceable even if somebody finds out one of your addresses.. That's one reason asymmetric key cryptography is a core part of the system. If you're only using exchanges, on the other hand, enough legal bother could expose you entirely. But that's probably the last of your problems, in that case.

Or did you mean something else?

Doh, you were just making a joke about the earlier conversation. This has not been my best morning. But @jackc might want to hear it.
