For some months, cryptocurrency is in a down falling trend which is the main cause.
It is pretty strange for BTC to stay in the red zone continuously for several months. But this is quit normally because many people earned a lot of money in back 2020 so now the market is cleaning shit projects and shit holders. There are more than 12k coins in the market right now. What do they do? Most of them just make the same thing with a different name.
