I really bet to disagree with your point. Bitcoin too can be called centralized in this context. Satoshi Nakamoto holds 1 Million bitcoins, which is roughly 5% of the total supply of bitcoins as it is 21 Million. This actually is too much and enough to actually call this coin centralized as well. Infact some other cryptocurrencies have even less promoter holding than this. But yes the only advantage here is that one the creator is anonymous and secondly it has not moved even a single penny from what the holds so far which indicates bitcoin is quite safe to hold and obviously much better than the rest.
that he's still living and rather give out that kind of boost up and so much trust in bitcoin although there are some cons with it which some people might be thinking that he came back just for him to sell off this bag
which might create some fud and panic on the entire market although we cant be sure but the probabilities are there and we know on how peoples mind do really play on these particular times.
For now lets just not stress ourselves on finding satoshi because it cant really be known whether his still existing or already dead.
