In order for bitcoin to grow above twenty thousand, it is necessary that there are a lot of buyers and that there are more of them than sellers.
It seems to me that all those who wanted to buy Bitcoin have already bought it and there are now fewer buyers.
Each time when I start to believe that the market is ready to start the bull run, the next day comes, and the altcoins are falling again. I cannot call it the bearish trend. Simply the market is not stable now.
