My personal hypothesis: By 3rd/4th quarter of this year we will see ETF's, options, leveraging, etc come into the market. Once this occurs major Wall Street firms will start trading. This will create volume at levels never seen before and drive the price far, far higher.
They'll trade paper bitcoins that they can't back with real ones, and keep the exchange rate artificially low just like they do with gold.
Q4 is the earliest possibility of a ETF right? And when do projects finish in time? That's right never, so I'm assuming 2015.
