Bittrex is adding Ethereum Classic. It is already there, but disable.
If you go on your wallet on Bittrex and search for ETC it will be there but it is disable so far. It will probably be running soon.
It is very confusing what is happening to Ethereum right now. I'm moving some of my stuff to Steem as soon as the price shows some sign of a recover, or hit new lows.
Thanks for reading.
