The 15k$ mark has already been overcome and now bitcoin is going to 16k$ and I think if everything goes on like this, then by the end of the year bitcoin will be able to easily reach the 20k$ mark, but it is not yet clear why bitcoin price began to rise so sharply, perhaps without any reasons big players just decided to raise the price of bitcoin in order to make money on it again, so it will be necessary to have time to sell bitcoins before the fall, and as usual dump will come suddenly.
