Creating the master key in a ceremony doesn't guarantee the computer isn't backdoored or someone isn't using technology to sniff over the air-gap. And no one will ever know if it was intercepted or not. It is impossible to know the money supply.

P.S. Just wait until DarkCoin's CoinJoin is denial-of-service attacked (if necessary I will do it to prove it is vulnerable, will wait until it becomes more popular then bet short on it and DOS-attack it). Tried to tell them that, but they didn't want to listen. Oh well. CoinJoin can't be protected against this because it is a two-step process (not atomic). Go read my debate with gmaxwell in the CoinJoin thread. Blacklisting input addresses is futile.
