2017's bull market made people consider everything a good investment, because everything was going up and paying out for quite a long period of time, even the most ridiculous looking scams. People become more aware of what this space is about, will look for better exchanges to use, and will eventually stick with just holding or trading the more established coins.
Regulated platforms will attract smart people. Unregulated platforms attract stupid people. Considering that there are more stupid people in this space than smart people, they will continue to get scammed, lose money, etc.
