Once I kept a few coins on a random exchange called BTC-E.com. One day I woke up and when I went to log in to the website to trade my coins, I found that it had been seized by the FBI. You might wonder how the FBI can seize a domain whose owners and operators are based in Eastern Europe such as BTC-E.com. Well, the same way they can seize a domain whose owners and operators are based in Malta.
