I think Token are falling down fast if the project is failure but ofcourse if the project is good and community are demanding the price target of this coin just hold even if you don't know the project behind it. just hold or buy more
Token price may fall or dropped even more when it hits cryptomarkets because it's the time where dumpers are free to sell their ICO tokens even just in Day 1. The more dumpers dumpers dump their tokens, the lower the ICO price of that token will get.
