I believe that bounty hunters partly to blame in this problem. When the project is listed on the stock exchange, they must be confident in the strength of their cryptocurrency. The project should provide financial support to its coin. Without such support, the coin will quickly collapse.
In most cases, each project and team receives funding from investors, but the coin is allowed for self-service. Because of this, ethereum has lost a lot of percent of its price, because the developers of Eco by the company you woke up the cryptocurrency from the market and cashed out the funds that I get from investors. It seems that everyone is worried about the amount of money, and not about the prospects of their coins.
