So, let me say that, even though we all are advised to never leave funds on exchanges, I personally will still commend so many of the exchanges that have shown honesty in their operations, even in hard times, they kept their integrity intact.
There are many cases of exchanges that are truly honest and dishonest, that's why sometimes everyone has different views about where funds are safe to store, I'm sure there are also some people who put their money on large exchanges, for example, Binance or other exchanges so that trust It also comes back to each individual, sometimes some people keep it in their personal wallet.
I also believe that people don't really put all their money in one place, let alone third parties like exchange sites, because of course they also understand about keeping their money safe so that it doesn't disappear, where in many cases there are exchanges that are bankrupt and dishonest, that's why it's best not to put them completely in one place. If you don't do anything, for example trading or gambling, you should keep it in your wallet, but if you should do both activities, there's no problem putting it with a third party as long as it's used for trading or gambling.
