What do you think I should do now?
If the token or coin has no price then nothing can be done. Because the token is valuable if there is a price. Exchange is the most important thing, if the token you have does not have an exchange, it is useless. We can only wait until the developer signs up for another exchange.
If the team is still active, They maybe Sign up for another exchange. But most of shitcoins were abandoned by the team after listing in the first exchanger. So it's impossible to sign up in another exchange. It Will become trash in your wallet.
Yes, OP should hope that the team will have a plan on listing this coin on another exchange or else, the coin will remain valueless. The only thing he can do right now is to wait and if ever that this project is already abandoned, there is no other way to sell it. The coin will remain in his wallet with no value at all.
