Bitcoin futures start trading on the CBOE at 6PM ET tonight. I think a lot of the run up in the last week is tied to this as a sign of investment legitimacy. You can now trade without actually having a digital wallet. On the flip side, it opens up the ability to bet on downward moves. Some believe the latter will destroy the price. We'll see. Currently at $15,115 as I type this. Many brokers are not allowing retail trades at all or no short positions and 50% margins.
