Institutional investors store their Bitcoin assets in a place that they think is safe. But often, these institutional investors hold their assets, i.e., Bitcoin, as collateral on centralized exchanges. And I think it is up to the institutional investor to decide which place is safe for their assets. As for Binance, many institutional investors have kept their assets, i.e., Bitcoin, as collateral, which makes them completely safe because the security of exchanges is stronger than ordinary online wallets.

In my opinion, the best and most authentic thing that secures the assets of an institutional investor is a hardware wallet. In my view, this is one of the safest methods, and it is necessary for every person who has Bitcoin to buy a hardware wallet for himself and store his Bitcoin in it like institutional investors do.
