I'm just asking because I don't want to be victim to the fucking after the flipping.
This alarmed me at first, but it seems to be cool, or its attached to the right blockchain at least, LOL. Was wary of a scam (I know that sounds paranoid, esp with Bittrex, but I have seen some shit man) and then was cautious about similar named coins (everyone else kept saying BCH while Trex had BCC). I can confirm that the BCC symbol corresponds to Bitcoincash, and Bitcoincash sent into the exchange will increase your BCC holdings.
Why the difference in nomenclature? No idea. Did Trex have a BCH symbol before they added Bitcoincash?
