This is a monumental step in getting Darkcoin accepted into the bitcoin community as the de facto standard for anonymity. This puts DRK on a level playing field with BTC and states that Darkcoin provides something Bitcoin cannot.
Plus thinking further ahead, this will open Wall Street's eyes to Darkcoin after Bitcoin has it's ridiculously successful ETF and everyone will be going 'I need to diversify the cryptocurrency portion of my portfolio...what other legitimate coins can we bring to market?'
As an aside, I wonder if we have discovered the identity of Mr. XosX?
