Maybe governments really start to do something. Scam is a scam and scam should get you in jail.
This is a really good point.
China already started something about regulating ICO.
All the crypto world would need to get clearly regulated. And then the really good projects will go on, they'll mean much more money, and the garbage will stay in the bin, else the fake devs will face the chance to go to jail.
Unfortunately I feel like most of the ones that could regulate cryptocurrencies don't understand them and are afraid of them.
