He just stated a fact that's all, and he is right. MagicTux(and his staff if he has one) is the only person with eyes on everything. Even the dark pool orders can't see other people's dark orders
Indeed, which is kind of the point of my OP, to have a public debate on this. If one would be far fetched, it could be claimed that by setting darkpool size, Tux can directly influence the price of the publicly traded BTC, much like a Central Bank can use prime rate/federal funds rate to adjust the market indirectly.
