if satoshi nakomoto mined 1 million bitcoins in early days. who own the second worlds biggest bitcoin wallet?

It is difficult to know who own the second worlds biggest bitcoin wallet, but may be someone in the dev group that creates bitcoins.
It is really a very difficult thing to tell this thing. There are so many people who claim this thing that they owns the worlds largest bitcoin but no one actually knows the truth. I consider that person to be the luckiest person who has managed to gather most of the bitcoins, in fact much more than anyone else in this entire world. He will for sure going to become wealthiest person in the future.
