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 ?
You would better not do it, but in a such situation you can send them a link to all transactions that you performed with your bitcoin address. For instance, like this one:
