I have sold some bitcoins with my paypal account, and now Paypal is asking me for clarifications for the bitcoin transactions.
What should I tell them ? I guess it's not allowed to deal with bitcoins ? What will they do if I tell them I sold bitcoins ? Can they refuse to give me my money ?
Whatever you do, don't lie. You will be in very big trouble if you lie. This is a federal crime and you'll get done for money laundering. Just like those two guys in Florida - Jail is soon in your future if you lie. Don't be an idiot.
