I'm pretty sure that mtgox publishes trade data back to the beginning of time, so if you are interested in replacing your faith with evidence, you should be able to figure out how to come up with a reasonable estimate of how much income mtgox has generated.....
You do know that adding more supply to a market lowers prices, right? And so in your hypothetical example, if they decided to sell, it would make the price go down, and not up.
I dont have to supply trade data to back it up. All I do is say each trade is another hoarded coin. Then I say over the long run without ceding market share, they win. A monopoly that becomes too big for its own good. I understand you are in it for the short term so you dont care.
