Well, I don't think it is likely that someone could become the world's largest Bitcoin owner or holder (or take Satoshi Nakamato's spot), because, as I know that wealthy people rarely put all their money in one basket, perhaps because it is too risky for them. However, if we are talking about companies, institutions, or countries, I think it's still possible for them to become the world's largest Bitcoin owner.

However, there is actually a big lesson we can learn from this: we can see how, if we try to hold Bitcoin long-term, it requires patience, making installments on Bitcoin to save, and I think the best way is with the DCA method, so we can use our money efficiently and profitably. And can you imagine, did it take Satoshi that long? I don't think so, because it is well worth for the increase in value.
