people also don't understand (unless im wrong) that when you buy GPUC from an exchange (too bad theres not a big major exchange..) the price you buy up to increases your holdings instantly to that value if you are going to use it to buy a GPU, as in you don't have to try to sell your GPUC at the going rate, its instant to the site for a video card for that rate (if it updates quickly enough). A few BTC in sales could easily sell out those remaining GPUs if a few BTC brought the price up to 40-60+ sat

Edit: I guess unless it follows only the buy orders, but again, its easily manipulated, depending on how long the site/store takes to update the price.
