My experience had nothing to do with blockchain congestion. They just put me through kyc hell. Asked for a bunch of selfies and took a month to finally verify the account. I'd send them a selfie and they I have experienced the same. I had to touch my nose, rub my belly and take a clear picture simultaneously only for it to be rejected. I wonder why they play that game, as I was withdrawing negligible amounts. If they alleviate the payout issues, they would be in line with the other top books. They're not as illiquid as it seems, but if a few give up, it adds to the bottom line. Otherwise, it would be an excellent established book to play.
