I just sent KEY from my wallet to Bittrex and it took about 6 minutes. Not sure what's happening behind the curtain, but that was an incredibly FAST transaction!
Let me clearly clarify just to be clear:
It was not in my "pending deposits"; It was in my "available balance" at Bitrrex in 6 minutes!
Because Key coin is no shit coin, and crypt is legit too. Prometheus backed coins are innovative coins, just wait and see.
