Although ICO investment, but is profitable it is very difficult to find out a real and successful ICO. Because there are a lot of ICO here. A lot of ICO is coming in every day. Most of the ICO's are scam and unsuccessful. That why ICO investment is very risky. So, you have to study a lot about that ICO you want to invest there. So, my suggestion is taking some time to understand the market trend and ICO investment. Otherwise, you will lose your capital.
