Yes crpto scam is a global issue since cryptocurrency are global currencies but the fact is before we have agency that will help in the tracking and preventing this occurrence it have to go through the government and as we all know no country have fully accepted cryptocurrency as a legal currency within they jurisdiction.
If the government had been in supportive of cryptocurrency the issue of global scam would have been addressed we have FBI, CIA, INTERPOL etc these are government backed agencies that can track or arrest those behind those fraudulent activities however government across some countries had shun and kick against using of cryptos these had really encourage scammers to have a field day in carrying out all those crimes unchecked.
