And if I withdraw them into trust wallet, can I exchange them in-wallet into ... something more useful?
Or is there someplace I can exchange those tokens?
I guess that I'm not the only one that doesn't really care about Trust Wallet, nor their token, but don't mind for a small present.
You can swap the token on Bianace DEX for now becasue they are yet to be listed on Binance exchnage. Although there hasn't be any official announcement about this token in exchnage but there are pretty good exchanges it has be listed. Personally, i feel they are likely to get the token listing soon on their Exchange according to some rumors.
