How would you know that the coin is worthless? The fact that it created and distributed that's mean it will have value in the future. Failed project would not distribute token, I think (am not sure at all) newly created token has a fee on the block chain ecosystem before it created. Further, the gas pay that the project would fee for transferring the token has its value. So, they have invested money for it. If I were you just hold the token in your wallet and wait for exchange.
