Funny if Satoshi is to be revealed, it would be in a TV show and He an individual whose identity has been hidden for years would star in it.
This people are really taking us as been stupid.
Vitalik Buterin is present, known and giving interviews, yet we have not heard that Ethereum has become centralized because of his presence, so if Satoshi returns, Bitcoin will not be centralized or affected by decentralization except by what the miners and full nodes will decide. Satoshi's influence comes from the fact that he can access a lot of Bitcoin, and estimates indicate about a million Bitcoins, which means that he will negatively affect the price because these Bitcoins, so far, are assumed not to be moved, but the presence of Satoshi means that it is possible to sell these Bitcoins.
But it's presence though wouldn't change the decentralized protocol would make Bitcoin susceptible to things affected by centralization.
Anything he says could be taken at an higher esteem by many users and would make him like a Face of Bitcoin.
It's price could be affected if something happens to Satoshi and would take a massive dip if he's taken into the custody of the government.
Well This would be temporary but would still be a pain in the butt.
as long as the person is still alive, eventually that person will be found, but in cases where a person dies, then they are not found.
Individuals were found after death and there are individuals that were never found alive and after death.
What would he gain coming out of hiding?
Fame?
Money?
He has more to loss been in public than in hiding
So it was smart of him been in hiding and still his (if he's still alive though).
Not all Government have accepted Bitcoin.
