Yes, I also agree that now you should not buy bitcoin when it is at the peak of the price. We need to wait a bit and I think in the near future there will be a correction to 4000-4500 $. But it is not exactly.
Possibly...
With every rise in the price of bitcoin aktiviziruyutsya trolls. They do not know that this attack will not stop? But even if we assume that bitcoin price will drop to $ 4,000, that would be 4 times the price rise for the year. As it will stop new users. Give me an alternative to bitcoin. It is not and therefore, bitcoin is coming.
