I agree that the SEC are looking progressively less relevant to the cryptocurrency market as time goes on. How many failed BTC ETF applications were there? And now they're hoping people might take seriously their latest equivocating response ("BTC market is manipulated"). How many SEC administered markets are regularly manipulated by former and future SEC senior employees? They hardly have the cleanest shirts when it comes to dirty markets.
But the SEC is relevant in other ways; the other (heavily rigged) markets they oversee. Bitcoin needs a solid trading platform that trades commodities and equities with BTC denominated contracts before it can completely transcend the SEC. It will be amusing to take their client base away in such an event.
