The recent hack also makes the point clear why we need to diverge away from Binance. Depending on a single exchange for our trading needs would hurt us one way or other. If we just diverse, we'll be getting lighter blows.
I agree, even if binance is the most widely used exchange around the world, it is better to use several exchanges than to use just one, while this means having several accounts and making sure that each one is properly secured, in the case of a hack to one of those exchanges your losses are going to be limited to only a fraction of your capital, however what we really need is that decentralized exchanges become more popular but I do not know what it will take to make traders to wake up to the reality that centralized exchanges will never be completely safe.
It is better to store the funds on the Ledger, only several percents on exchanges for trading
