Hello , a friend of mine got some dirty bitcoins.
And, of course, you have to help him out because he's "your friend". I mean, that's what "friends" are for, right?
what if he sell the bitcoins to bitstamp and buy new bitcoins from bitstamp.
He got clean coins now and he can cash out without getting traced to criminal activity??
Until BitStamp gets a subpoena from either the cops trying to trace the dirty coins, or the taxman trying to trace where the cash came from, at which point the connection between the two will be revealed.
If a bank ask him how he get to the coins he will say from gambling on a tor casino ?
And if the bank asks him for the transaction ID of the winning wager, he'll be able to provide it, because he was smart enough to plan ahead and send a small amount of coins someplace prior to receiving the larger payment? If not, he doesn't (just) need a mixer, he needs a shady accountant to help him come up with a more believable story.
