Thats about 24 months in business.
In their indictment, the government alleges that 1M of that went to Silk Road. (I wasn't even selling BTC to Silk Road users, I was allegedly selling to a guy who in turn resold the coins to users on Silk Road for a markup )
That means over a 2 year span, 0.025% of transactions on BitInstant were for Silk Road.
BitInstant's total operating profit (before costs, expesnes, ect) on 1M USD is 1.5% = $15,000 total the company profited from these alleged crimes, over an 11 months period. Thats $1,363 per month.
Charlie was doing pretty much exactly this (granted he was making more money from it) but the only other real difference is that he was profiting from and helping SR.
I personally made no extra money from these alleged crimes.
Hey, Charlie - thanks for the great service. I never used Silk Road (haven't ever done drugs in my life, though I affirm everyone should be legally free to do so), but I used BitInstant several times last year. It was fantastic, and I was sorry to see it go. I hope your legal woes will soon be as far behind you as they can possibly be.
