But lately he has had his friend use my PayPal account. Someone will send me money and then I transfer it to where he tells me. To cash app or venmo.
That's money laundering. Definitely illegal.
He said it's money owed for cellphones.
People in jail aren't supposed to have cellphones. You are helping him break the law, which means you are helping him ...
When does it become illegal to exchange bitcoin for cash?
When the transaction purposefully skips the controls in place regarding anti-money laundering.
Generally speaking, the issue is not the mere involvement of cryptocurrency in a transaction, but the crimes a wrongdoer seeks to camouflage or conceal by means of cryptocurrencies. Such crimes typically ...
