That's right, we don't know. But that's the beauty of bitcoin, that our knowledge doesn't matter. Satoshi Nakamoto remains the owner of his bitcoins whether he wants to spend them or not, whether he is alive or not, whether we want him to spend them or not. He has full control over his bitcoins. And no state or organization or anyone else has the ability to influence this. Only theoretically the entire Bitcoin community, but it will not do this.

If he is alive and has access to his wallets, I hope he checks it and he has backup in case some of his computers get broken. Ah, what a mystery. We don't even know what is his real name. Where is he from? He is turned into the first and biggest example of being anonymous and how bitcoiner should remain. He gave us financial freedom and anonymity with Bitcoin, and we invented centralized exchanges to ruin that. Gazeta said
