One more thing that has a lot of impact on ICO projects is that they offer a faint idea and the market is bottoming out. there are too many negative impacts for ICO projects. But risk will come with great profit. If you are good enough to know what you should do, invest in really potential ICO projects.
for now, most ICOs don't have prices that match their whitepapers, or their targets. whereas, if you think back, the softcap they target can make the price normal, but for now I think many ICOs don't care about softcap, and always extend the ICO they make themselves. well, because that's the ICO at risk.
To some how you are right but I want to tell that if an ICO project manager offers more than expectations you should understand that this may be fake and they will disappear from the market after collecting huge funds. When a manger is credible and he offers fewer benefits to its investors, you can trust him and his project and can put your money in that ICO.
