honestly you should make sure that they really charge or not, maybe chat them again $40 just to retrieve your own money is honestly ridiculous but there is also always chance that some business enforce such a thing to make sure they aren't losing on other people's mistake.
you just need to make sure that the email you received is genuine from kucoin and if it is, then start to think whether it's worth it to retrieve your money by paying that fee.
honestly if i were you if the money retrieved outweigh the fee imposed i'd just retrieve and dipped and never using kucoin service again.
to be frank though,i personally find sending coin to a chain that requires memo to be a really bad experience and really vulnerable to mistake, our muscle memory always thinks an address is enough identifier.
Because asking money to do things before they do it, is excatly how scammers operate.
Exactly and that is my fear and nothing more. Frankly speaking to pay the money nis not an issue, if I pay the money then they frame another story that they can't refund the money because they don't know where the funds are or other cooked up stories then I became a loser with double transactions. So the payment before refund is not nice one. I really doubt if it is real.
yeah requires paying before knowing whether the problem could be solved is really an shady move in my opinion.
