The thing is, do we know for sure this didn't happen?
I have no way of knowing whether or not this was actually the case; I was just speaking more broadly, that if there was no banner, then there should have been one.
I refuse to believe that Gate.io did not put out any warnings on the deposit page or even totally disable generating the deposit address as most exchange do once they announce that deposits have been suspended.
This is the same guy have the same issue with phemex too. I don't think it's a coincidence.
Any self-respecting entity would put up a message about services being temporarily suspended, maintenance messages have become a standard nearly everywhere and in every industry. I'm hoping that lotfiuser is just mistaken, and that this isn't another exchange operating beyond poorly. I still stand by my statement about avoiding exchanges like the plague, though.
If this user is having this problem with multiple exchanges and nobody else is having these issues with either exchange, then it's probably safe to say that it is a user issue.
