That is quite risky, but I understand since I do the same. Also it's easy to trust Binance since it has never been hacked.I don't keep my crypto in wallets, I keep them in exchanges. Well, I understand the risk of keeping your assets on exchanges, however, I stake my assets and earn daily rewards from my assets. About 90 percent of my crypto assets are on Binance.
CZ also is doing a great job with the exchange, making a lot of people to stick with it.
If I were to have a lot of coins especially Bitcoin, I would move it to trust wallet.
