For most ordinary people, this limit is not a problem (at least not for me), although this other thing with bank data is not something that some people would want to do, especially those who are looking for a much higher level of privacy.

However, if you trade through DEXs, you always have to count on someone seeing your bank details, even if it's just the person you're trading with. In most cases, these people have no bad intentions, but you never know if the other side is someone who just wants to trade, or has some other intentions - it's no secret that various agencies insert their agents to pretend to be what they really are not.
