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.
You might be correct here $60,000 does sound likes a very realistic price for 1 Bitcoin.
But i do not think it will have anything to do with Satoshi Nakamoto buying more Bitcoin to push the price up. I think he has moved on.
