I noticed that ICOs that list their tokens on decentralized exchanges can hardly have those tokens hit the ICOs price. Almost like D.Exchanges are killing token price, are they responsible for such
These are only bounty hunters dumping their tokens, you need to wait tokens to be listed on centralized exchanges, especially big ones and then their price will increase. Or read roadmap, usually projects will be launched 1 or 2 years after ICO so it is long term investment and you should wait for long time before their price go up.
