"All told, the site has generated sales revenue totaling over 9.5 million Bitcoins and collected commissions from these sales totaling over 600,000 Bitcoins. Although the value of Bitcoins has varied significantly during the site's lifetime, these figures are roughly equivalent today to approximately $1.2 billion in sales and approximately $80 million in commissions."
Does this mean that 600,000 BTC (give or take) is off the "market"? Holy crap - if those coins are gone, the value could skyrocket!
