No way. I believe that ICOs will play a big role in 2018 especially ones that are actually successful.
I do not think that ICO will disappear so quickly and disappear at all. Certainly there will be changes in the legal part and form of presentation, sale. And this is necessary to protect investors from scam. There is really a lot of scams. However, the idea itself is very good. It opens up great opportunities for both the founders of start-ups and investors. Almost any person can participate and make money on this, legally naturally.
