In my opinion now better buy and HODL TOP 20 coins. Not buy temporarily ICO tokens, because them price very strong less after ICO.
of course there always a momentum where the price will come down temporay as the roadmap isn't running at the moment. after ICO end, team of the ICO project should prepare and make everything is on its place before its moving on. and then there always a people who trying to sell and buy below the ICO price. no doubt.
but if the ICO as roadmap already running, then we should hold it. just HOLD.
If you ask my sincere answer, regardless of what state is in ICO, it can never bring huge profits. If such a project proves to be successful, even then a person does not earn any reasonable amount. I have never ever recommended this stuff. Getting good profits from crypto world is a lot easier and quicker than this. Buy a coin that has shown high values in the past and hold it for long. This is the right way to deal with it.
