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 can believe other reason but not this kind of reason, why would he buy and when he is already had close to 1 million of Bitcoin that is if he still has access on the wallet, where he store it, and what made you think he will I just don't see the logic, price will go up because institutions and whales are coming and new investors are buying too.
