As per past experience of investors, ICO has earned a really bad and negative image. It is very difficult to judge authenticity of any ICO. Whitepaper, Initial Plan, ICO review website can only give you an idea about their success but noone can guarantee you about their authenticity. Being decentralized, No Govt body control it or check it before launching. Only factor that matters now a days which encourage any investor to invest in an ICO is their TEAM. If you trust their team members and have faith on them after checking their track record,then you can think of investing in it otherwise don't.
