So, next time when someone tells you that Crypto currencies are used for scams, please highlight the fact that most scams are still being done under the nose of the regulated financial industry. 
I read somewhere of a report stating that according to facts, a great majority of all the scams perpetrated every year is done using the fiat money and only a certain percentage is done using Bitcoin or cryptocurrency. This is just the case of sensationalization since Bitcoin is relatively new unlike the fiat money which has had been here for centuries. Once a country is adopting its own regulations on cryptocurrency, scams can be investigated, traced and have the perpetrators punished.
