There is a scam going around the net from irc to twiter. Yobit has a Dead coin that is worthless that has DRC as its market tick. https://www.yobit.net/en/trade/DCR/BTC
be aware from yobit!! just google it, only scam report. wait to a better exchange like poloniex or go bittrex.
try it on day one. Both withdraw and deposit works fine. But is a very small one so deposit at your own risk!
That coin is DeltaCredits and maybe coin is dead but it still has a community & dev and they have explicitly asked not to use their ticker many times in BCT thread of decred. I hope devs solve this situation by talking to them.
doesn't matter, they were already listed before us on the exchange so they have the first rights to the ticker. Also public announcement of decred was after August 2015.
