Interesting. He makes it sound as if the SR economy is as big as the Bitcoin economy. It makes me wonder if Bitcoin really is primarily a vehicle for SR type trading with some small-time legitimate business frosting on top to make it look legit.
I'd say this is true. Maybe not drug dealing necessarily, but gambling makes up the majority of transactions. Certainly, most of the time if people want an "anonymous" (or pseudonymous) transaction they are not buying something completely legitimate.
