Let's just say that the value of BTC were to continue its pattern from the last few years.  If that were the case, the value of BTC would spike dramatically over the winter of 2014-15.  

-Now, how would a person acquire a large sum of BTC before that happened?  
-How could that person ensure that the price of BTC was suppressed just long enough (you would need a lot of BTC), eventually removing the walls and enabling a quick, emotional bull ride?
-What if you could tie up so much BTC on the market, that investors would be unable to sell off BTC during the pump, increasing the speed and height of the BTC price climb based on the appearance of unavailability and apparent demand.
-Perhaps you wouldn't even need to acquire a large sum of BTC, maybe you could just borrow it for a while...long enough to make a profit and then give the BTC back.  (like butterfly labs!)
-Now, where could you get (borrow) millions of dollars worth of BTC?  Could you make people believe that they had a lot to gain by letting you borrow hold their BTC right before the value of BTC skyrocketed?
-What if you don't know the exact date that BTC will rise, but you have it narrowed down to the winter of 2014-2015?
