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.
This behavior is nothing really new for bitcoin, after the bull market comes a crash, that is the way it works in this market and people which have been around for some time knew this was coming, now we have to endure a long period in which bitcoin will not move much for years and we do not know if this time around things could be even more difficult as the economies of the world are facing many challenges which they will find difficult to overcome too, so people need to accept the idea that they are going to need to hold their coins for a long time before they see any profits.
