all ICOs like that, the price of coins after entering the first market prices will fall by tens of percent and to rise again takes months but if the ICO is a good project the coin price will rise higher than the ICO price so I think ICO is not bad and not too nice
Therefore you don't treat ICO or any project that raise through crowdsale a short term project, you invest on them for long term as you believe the longer they live their will be progress. Actually only hype that will make the price grow in short term and therefore i can say you cannot find success in short term, only the day traders will benefit the movement as most likely a project that is hype is also overvalued.
