how many BTCs are owned by Nakamoto.
Satoshi Nakamoto has 1,000,000 bitcoin in his/her bitcoin wallet.
Given the fact that satoshi wanted to stay anonymous I dubt that we are going to see this.
One possible scenario is that satoshi will never move his bitcoins from his wallet to exchanges, because it is a given that will give away his identity to governments(especially if done on a centralized exchange like binance). One viable way for satoshi to convert all those coins to fiat is via decentralized exchanges and peer to peer transaction. When that happens though, I also think that many people will panic sell.
