Most of the reasons you all have indicated is clearly the reasons why the prices hit so low on exchange. But if the team behind projects are competent enough on what they're doing, they could bounce back the price. The problem is the team behind each scam projects are just focusing on and before the project is listed, and not minding what will happen after it hits exchange. Those all can be prevented if the project are well planned including the factors that would affect their coins/tokens AFTER it hits exchange. Right now, I still have faith on ICO projects based on the team behind them, currently I have been following EOT and MENLO.
