There is an entire website that lists which addresses own the most Bitcoin. You can find it here: https://bitinfocharts.com/top-100-richest-bitcoin-addresses.html

edit:

Why does the balance on blockchain.info is not the same?? All the richlist address are almost empty on blockchain?

thanks for this. Changed the site to accurate one.

How come I cant see satoshi's 1M btc on that list?
