It can indeed happen, which is often done by Sandra at this time, they usually prefer bitcoin as a means of payment may be due to the ease of existing in bitcoin transactions.
who is that sandra youre talkng about? They maybe used bitcoin because bitcoin is fast and anonymous when compared to fiats although fiats can also be used when doing illegal activities such as extortion. Also , criminals prefer to use bitcoin because bitcoin cant be charged back or irreversible after paying someone , not unlike to paypal , payza , payooner or any other payment methods online. Bitcoin doesnt also uses credentials or important infos before or during you make a transaction. Those are few reasons why bitcoin is the best for illegal activities.
