That, and perhaps Cryptsy was also bribed with insta-mined DASH to delay adding an obviously superior competitor.
We know Cryptsy has zero ethics because:
1) they ignore the votes and BTC in support of adding XMR
2) they conspired with GAW/JoshGarza/PayCoin to perpetuate the 'PrimeController' cloud mining fraud.
'Prime Controller' sounds a lot like 'MasterNode.' Both HYIPs promise to deliver gold donkeys via centralized PoS. What a coincidence!
Now that KoziTwo's payment gateway is done, Cryptsy has no excuse for XMR's conspicuous continued absence.
