Interesting thought, but mining profit margins are rather thick right now in most parts of the world (because the supply of miners is a little inelastic--mining equipment doesn't just poof into existence as the price rises). So I don't think anyone is turning miners on or off in response to small movements in the price right now.

Also, if you bought and then sold that would seem like a wash. Or worse, since you temporarily raised the price and therefor incentivized mining for that time.
