Hmm, greatest ICO has 95 % to fail you , because many of them are scam. If you find one , please let me know.
It is not true. There are a lot of great compaings, simply you should try to find information about it on special sites like icobench and others. I can advice you to pay attention on campaings with rate >4,3
Projects that benefit the participants, and to attract investors must also have teams and managers with big names. This is just my prediction, ICO potentially large crowdsale results and has a clear roadmap
