Go home Wall Street boys. You can`t tame Mr Bitcoin.
No guarantee that they're trying, or that they all believe the same things about BTC's current state.
They did't tried to tame it. I'm sure it is more like gambling for "Wall Street boys" that is not even popular and everything is done in USD and not BTC. The only good thing in those bitcoin futres is that BTC technicaly became legalized in the US as a financial instrument.
