I do believe that the Bitcoin price will rise very faster in the year 2021 because Satoshi Nakamoto is going to buy more Bitcoin to push the price up. He has got plenty of money to play the Bitcoin game to take the Bitcoin in its next stage.
I am not so sure if Satoshi will make a move in this crucial time knowing that he is hiding his ability all this time but your prediction is not impossible to happen also knowing that the big investors are favoring bitcoin over other currencies so if they will continue buying bitcoin in the year 2021 then hitting the $60k bitcoin price will surely to happen.
The bitcoin price increase is very fast and I didn't expect it to be like this as I was monitoring the market for several years already and it is the first time that bitcoin price increases that much in such a short period of time. Bitcoin has created a new ATH already while the other currencies are still battling to in reaching a new ATH.
