Someone made an analysis and claims that the bitcoin reserve is sitting on that address: 3M219KR5vEneNb47ewrPfWyb5jQ2DjxRP6

There are indeed over 90k BTC there.
When i look at the richest adresses it says Binance cold wallet.

Have no idea if the analysis is true however. Take it with a grain of salt.
