each exchange has its own differences, I see that currently the most prioritized is the transaction fee. if an exchange has a small transaction fee I think it can be faster to develop than an exchange that has a high transaction fee. This is what many people talk about nowadays.
But what if the exchange has the lowest commissions, but there are many reviews regarding this exchange that it freezes accounts, or funds disappear from the accounts? Of course, all this can be avoided if you do not store your funds on the exchange, which will be the most correct decision. Probably the commission indicator is not the most important, although many people certainly pay attention to it.
Indeed, commission is one of the considerations for choosing an exchange in certain situations, but for me the security of funds is the most important, especially for those who use large funds, so they will prefer to use a trusted and recommended exchange. but for small-scale transactions, I personally prefer to use exchanges with low fees, but I don't put long-term funds there, I even withdraw them directly to my wallet, to avoid unwanted things
