Satoshi has a
balance of nearly 1 million BTC, let's guess what will happen if the wallet can be accessed by someone, whether it's the owner or maybe a hacker. Will the price of Bitcoin start to crumble and start not selling?
If a hacker gets a hold into this fud news will flood the bitcoin world and surely with that most people will start selling bitcoin. Not totally crumble I guess maybe a major dump would happen if this where to happen but its most unlikely to happen because its been almost a decade and still hackers can't get a hold of that wallet address.
There are a lot of possibilities, satoshi could've forgotten about that 1 million bitcoin and never bothered to find it, that seems ridiculous but that can still happen. We will never know because we do not know who is behind the curtains of the account satoshi. Best thing we could do is honor satoshi's wish to be anonymous and cherish the brainchild that is bitcoin.
It is indeed possible but I think he will never forget that he holds that amount of bitcoin in a wallet. If I where Satoshi and created something really valuable like bitcoin there is no way on earth that I will forgot about my holdings.
