I think 70% ico's are scam they just copy others white paper and publish it and owning itself its quiet hard to indicate whether the ico is good or not better yet always ask the ico readers if its good or not.
Good point! I just realized today that over a half of ICOs offer a 'faster blockchain' decentralized infrastructure for dapps blah-blah-blah with the same specs and so on and ask for millions of dollars whereas you can make one by just branching Ethereum and changing target block time from 10 seconds to 0.1 seconds and you're good to go lol.
