This is not a joke, it is real, and those users who are not yet complaining might maintain and transact a small amount with them which will still shield them from fraud. Even saying they have the fastest transaction (if such a statement is real and not fabricated by you) shows that the person is naive, there is no centralised exchange that will do less, except that it is even worse with Freewallet because you will have the opportunity to set the priority. For this, it could be slow if you go for the low priority as they will not do any magic in the blockchain, unlike most exchanges that are sending your crypto without the option of priority, which means that it is not optional so it must be fast.
Above all, I see no joy in holding your money in a centralised service like Freewallet that doesn't even have the features of the main exchanges (businesses, spot & futures trading). People are better off moving their money to self-custody instead of this.
