I would recommend to wait until an ICO is coming to an exchange. Only few ICOs at this year could gain profits, 95 percent of all ICOs got a big losses for the investors. So if you are interested in a coin, just wait till it will be live on exchanges and buy much cheaper 
I agree. Even ico got 50% you can experience to lose your money because after it list in exchange for sure the price can drop and that is the reason why many people invested in ico got lost.
