What is the token name?
Maybe if you can tell the name and where it is listed, we can suggest something.
You should search for how to convert into popular coins such as BNB, ETH, Polygon, TRX and then send it into Bittrex, Binance or other popular exchanges.
If you can send it into another wallet, that will be the way to convert it into other coins or tokens.
That is the only way you can cash out your token.
I am sure there is a way for you to convert the token to popular coins.
