And very stupid because bitcoin is very easy to track on the open ledger so they should have put some time to find out which addresses are his so they know how much there is to take.
How were they supposed to do that, if i don't post all of my BTC addresses, how can you know the coins i own, this barber may have boasted to be very rich in crypto, but he may never have posted his addresses to the public. All the information 'crypto kidnappers' need is the status of their potential victim, once they can ascertain that the victim is a popular figure in the crypto industry or poses as a rich person in crypto, they can attack.
