I think the whole thing is pretty scary actually. I see futures market as the introduction of reason and technical analysis that is going to wipe a ton of the last couple weeks gains right of the table. There is as much incentive in that market to crash the price as there is to see it rise. On the positive note is that it will eventually bring stability and start crushing out the volatility.
