Satoshi Nakamoto has an untouched Bitcoin since 2010 with an estimated amount of about 1.1 million Bitcoin with Bitcoin having a total supply of about 21 million Bitcoin and circulating supply ( 19,906,243 ).
Now here is the question, what would happen if Satoshi Nakamoto withdraws all his Bitcoin.

I guess this has being a popular question with unpopular perspectives but to throw more light into this. No one has any information on him as he remains anonymous with his last message to Bitcoin developer Mike Hearn saying "I've moved on with other things, it's in good hands with Gavin and everyone"

Research has it that he is responsible for the "mega whale wallet" massive transaction as at 2010 and suspected he hasn't gone off but tactically cashing out since 2019. He has being known for his intelligence and analytical thinking and wouldn't see it fit to withdraw all his Bitcoin at once causing a drastic decline in Bitcoin's price.

The market would experience a major fall as he holds about 5% of Bitcoin's total supply with other cryptocurrency being affected as Bitcoin has being seen to be the father of all of all digital currency. But Bitcoin being a decentralized exchange that nobody can control and having a high demand would definitely bounce back I know.

With this, I think Bitcoin has full potential to bounce back after a massive reverse just if Satoshi Nakamoto withdraws all his Bitcoin.
