Yes, most of ICOs give very littel ROI recently. And most of them will leave you without any means for survival. But the trick is to pick the right ones - with brillian team and perfect concept for technology. Check Metronome for instance in the near future, they will be conducting an auction, Dfinity will be giving an airdrop for the early community supportes. My picks also include: Egretia, NEX and Merculet.
Good luck to all you guys!
