Just try searching Binance on Etherscan and you will be surprised to see the results. The biggest portfolio are usually hold by exchanges. There are over 1000 coins worth more than $200M on Binance's ETH address.
Just checked it out, thanks for letting me know the website.
Tbh, I won't be surprised by an institution like Binance to have gazillion coins, but this is a random bloke I was talking about who started really early and is reaping the benefits now.
