yes because they are shitcoins ;) they work like this:

they create a lot of hype for investors and lure them with sky-high APR or other lies, building a lot of hype and tension among them even before the coin is released. When they are released, investors load up the money and the creators slowly start to withdraw and for a profit, for example, they add coins to the next exchanges for part of the profits so that the money flows.

They do not invest anything more in a coin built in this way. They do not develop it most often and it does not cost anything. On blurt, on the other hand, there are people who take care of the development and maintenance of the network and the network itself provides specific services. This costs money and it is a completely different level.

Btw, so-called shell companies on the real market that make a jump on investors' money also earn the most because fraud does not cost as much as real development of something ;]
