BarterDEX is an up and coming exchange related to Komodo. I think it's more community based and may be free to add.
BarterDEX is going to be a BIG thing now that centralised exchanges are clamping down and locking accounts. afaik they're testing 'etomic' swap tech at the moment which would allow atomic swaps between any bitcoin based crypto (i.e. uses utxo's, unspent transaction outputs) and Ethereum & ERC20 tokens. Not quite there with 'etomic' swaps yet, but getting close.
The Movement community should definitely keep an eye on BarterDEX, and everyone can start learning how to use an atomic swap decentralised exchange using current bitcoin based cryptos like btc bch etc etc They're well over 30K live swaps now, done by 100's of people with average tech skills, amazing stuff!!
