I have participated in many legit ICOs. They got listed in best exchanges but the value did not even increase even to the core of ICO price set. Do you consider getting listed is thier success. I say no. Yours?
If the icos you are talking about are legitimate as you are saying then you do not have nothing to worry, the reason the price is not going up has more to do with the market than with anything else, but if you are mistaken it is entirely possible the price of the coins you are holding will never go up and it could crash in the next months, so for the time being you need to trust that your due diligence was good enough to separate the scams from the legitimate projects.
