You know what's the best thing about Bitcoins?
It can easily be tracked.
The owner can easy track where his money was off to and after that ... police can contact that wallet company and dj something about it.
It's so easily trackable that I don't even know why the criminals choosed to do it.
Well idk what anyone will do... But that man can sure hire a private detective and get his investigation done and offcourse get his money back by contacting the police.
It's easier than fiat.
