One day ICO's will be regulated by law, but for now, it reminds me Wild Wild West. I did invest in two ICO's: Monetha and BlackMoon Crypto, and few more once Tokens was released to exchanges.  It's very risky and in some cases better is wait until tokens start trading on exchanges and price goes down after few weeks. Only best ICO's brings rewards from day one, some after time and few are never profitable or became scam.
