ICO is very risky but also high return if it is successful. It is depend on level of risk you want to take. I think it is also good idea if we do research on the ICO and milestone of the project. In addition, we can follow the progress of ICO and its price after 1 to 3 months on the exchange and review its work progressed before investing on it. I am not investor or trader of any experience in the market. This is just my views. :-) Be profit and have fun with cryptocurrency. Anyway, I am long on Steem and I like @Steemit.
