Its not yet clear if and when Exchanges will announce Calisto support.
Bittrex has been giving a chance to the developer but it seems the bittrex will not be listed CLO in the bittrex platform. Binance seems to be another major option for bittrex but yobit will be accepted CLO support instantly. 
My opinion is ETC will recover its price to 35-36 very fast after CLO hardfork. This moment price have drop because pump and dump team, they pumped ETC to 45-46 and then dump it...
Or even worst than it, How NXT gets dumped more than 90% just in some days after the snapshoot already taken.
