SecondMarket is buying up 1000 / 28,000 = 3.6% of the new bitcoin supply on a regular basis. Without the word "not" your bolded statement above is equally valid (and equally biased): they are big buyers!
Please people, stop quoting that guy. He consistantly gets "facts" completely wrong. I don't think he's stupid, so he must be doing it on purpose, ie trolling.
Second Market has bought over 100,000 bitcoins. That makes them in fact one of the largest buyers in the world.
I dont undertstand why we are still entertaining him as his motives are obviously not genuine....
