Forkdelta has varying volume but is still active and probably the best market for RCC right now. Sell orders/Buy orders likely to hit here but in a wide range.
https://forkdelta.app/#!/trade/RCC-ETHBlockex markets had paused trading but they should be coming back online soon too.
Token.store has no volume really as their user base is so low.
Token Market has recently gone offline due to an issue with their company/employees.
Talking with a few other exchanges but some of these seem to be smaller exchanges who lie about their volume (they say their exchange trades $1 billion per day and ask for 10BTC listing fee but really have low users and faked volume!)
Our applications to bittrex/binance/bigger exchanges were mostly ignored from '17-19.
