How to get money out of unsupported

Need help with some cryptos to know if I can use them or if they are useless.

I have Tribe 8 dollars

Tether 2 dollars

IoTeX 2 dollars

I tried to swap them to ETH but the fee is like 30 dollars. Are these tokens just useless now or is there someway to get at least some money of them? Not that much money but I am still curious. Thanks!
