For anyone who's directing their rage at MtGox for this, that should not be the target.<p>We should be outraged at the banking system and the lawmakers instead. They are the ones who are putting roadblocks on to MtGox, as these documents prove.<p>MtGox does not operate a MSB according to the laws in Japan, so if it has a bank account in the US, how does it make it a MSB?<p>Besides, the FinCEN guidelines are not clear for Bitcoin. For example, there's no clear definition for what is a "User" and what is an "Administrator".<p>Being P2P, users are administrators at the same time. (You don't necessarily need to mine bitcoins to be an administrator, if you're a user, then your client still needs to do administrative tasks such as relay transactions across the network)<p>Besides, bitcoins should be considered as virtual messaging service, rather than a currency as in the traditional sense of the word. In essence, Bitcoin is a distributed messaging network. (When bitcoins are bought, the buyer is actually paying the seller to send a message to the network).<p>We need better, clearer guidelines on this.
