This is actually an amazing story. Bitcoins have essentially become a new "racket" in the internet age. This is nothing short of an absolute corning of that "racket" in a relatively short time period. When you run the numbers it really is quite amazing, 2.2 Bil worth of overall bitcoins changing hands with an 80 Mil net for people behind the site in just a small amount of time (this past July-Sept). This site has been operation for multiple years. If you conservatively estimate total net profit they're easily in the billions in just commission.
