We must already admit that not all cryptocurrencies will grow in the future, most of the projects will simply leave the market
Most of these projects had just one purpose. And that was to make the promoters rich. And in most of the cases, the original purpose is realized. The promoters dumped most of their tokens after triggering the pump-and-dump cycles and in the end most of the tokens were left with the investors. The development stopped after the promoters made their exit. Now the investors have the useless tokens with them, and they can't sell these tokens as they have been delisted from the major exchanges.
This is what bothers me the most if all of those people left the market and they lost money then we will never hear from them again but they keep getting millions of dollars and the risk of getting prosecuted is minimal, with those kind of odds it is obvious they're going to keep coming back and they will keep scamming the people of this forum, but unfortunately they are ruining things for the few honest developers out there that want nothing but to help the market to develop.
