Satoshi can only become the worlds richest man when the price of Bitcoin rises to the corresponding height only if he or they continue to maintain this exact number of bitcoin in his or their portfolio for as long as Bitcoin continue to exist, but let's also not forget that there are still mysteries to unfold.

If lets say after 20 years from today, bitcoin is worth $10m, and non of all the bitcoins that Satoshi hold has been moved, what means that he or they have become the world richest, but at the same time, can we still believe that who ever this Satoshi is still alive by then?

But all the same, that's discussion for another day maybe, for now, it's a big celebration seeing how far bitcoin as come and it's fascinating watching satoshi climb the ladder of the most richest people in the world, let's hope he makes it to the top in fewer years than any one is expecting.
