No matter how carefully you choose, investing in ICO is like playing roulette. If your bet is successful, then you will make a profit (if you sell their tokens in time). If you miss, then your money flew into the pipe.
Behind any seemingly good team and project, there can be a dummy.
True even though they are transparent with everything they have done, but it doesn't mean they will leave their initial intention to either scam you or being a legit project out there. Most of the "active" projects out there have the same chance to get completely dumped in long run based on how they handle the response of the market and community. It's hard to invest in new projects due how they run the same method to scam us.
