So what are one's options? Imagine you had BNB or another altcoin and the exchanges that you allow you to trade it... you cannot have an account there. Are you screwed? I assume you could always find someone online who would help you sell it so to speak for a fee? Like imagine you give them BNB and they pay you via btc or stablecoin and you pay them extra to help you sell the coin since you cannot have an account at the exchanges which sell it?
The easiest way to figure it out through their official website or announcement to get information where to trade your coin . if all the information they provide is still not able to solve it, you can't help it through the Services Sub forum and trade with other bitcointalk members by providing their fee services. Don't forget to use escrow if you're not sure.
