In these days exchange is having traffic because of the calamity that happened recently on the transaction fee. Even in the forum we discovered that most of the campaign participants sent their exchange wallet address to managers to change the bitcoin wallet addresses. So with that many people are still using their exchange addresses for trading and other transaction activities.
Yes I will also agree with that keeping funds I'm exchange is at the owners' risk. Now that Binance is under a law suit and we don't know what will happen, so it is better the operators of the said exchange should not keep funds there for a long period.
Areas that propagate problems receive a great deal of attention from the public; everyone wants to know what problems are hitting the market. Crypto exchanges are struggling to deal with fraudulent operations that harm the general public. Fraudsters target the top exchanges to be able to decrease their functional requirements; some fight back, while others give up and crash to the dump. I don't think it's an efficient time to hold our currencies on exchanges at the moment because it's riskier than storing fiat money in banks. Binance is now suffering significant problems, but all will be resolved in due course.
