no we won't. because cases like this are mostly related to altcoins and altcoin exchanges which happen to be unregulated and unknown. and people will always use these, maybe even more in case of regulations. for example if exchanges in US such as Bittrex and Poloniex start being regulated and ask for hefty taxes from their users as they report all their activities to IRS, everyone would leave and migrate to other platforms and many of them being bad means scam cases like these would continue to happen, even more than before.
