Because until this very moment and with very bad market, some ICOs still can give you huge ROI%, I am down more than 50% on my trade at the moment and the only thing holding me together is one ICOs I participated in couple months ago and just 1 month ago once it got listed I made huge profit which I am relaying on at the moment . ICOs is always a good investment only if you know how to do it, Beside the normal research everyone gonna tell you to do, there is some other tricks if you follow it is really hard to get out of an ICO with lose unless it is totally scam .

p.s: Investing in ICO is more than just buy some hyped project and hope for some profits, if you do not know how to invest in a proper way, then you shouldn't consider investing .
