nothing is impossible especially for Bitcoin $ 15k by the end of 2020.
in the last few days, Bitcoin has continued to stay at $ 11k - $ 12k and continues to show good growth, it is not difficult to break $ 13k wall any time soon.
well, I also believe that it is not impossible. however, the bitcoin price is currently close to $ 12k. Even though it took $ 3k to reach that price, I don't think it's that hard when there is a pump in the rest of the month this year
