No i'm not talking about bitcoins
I'm answering the question about legality of terminating bank accts. Ofcourse its legal. Its their service, they have the right to terminate it if they want.
Heck they can terminate your bank account if you're rude to them.
Not quite. There has to be a legal reason to the termination. For bitcoins, with all the bad press of Silk Road and everything else, the banks could have it fall under illegal or misuse of the account and funds. Like how they freeze the accounts for criminals.
