I believe that the Bitcoin price increase has something to do with the fact that Christmas is only 46 days away! Was no one else expecting this as a result of the economic BOOM of all social classes going out to purchase their Christmas Presents ready for the event. I had already predicted to myself that the bitcoin price will increase around November 1st and will then go back down at around March 1st next year.
I think a lot of people expected a break up to around $360 (where Bitcoin is right now), and then some sort of correction. Indeed, the shorts started piling up at this price point on Finex, and no doubt on the Chinese exchanges also....which is precisely why Bitcoin shot up to $505. A great big dirty fucking short squeeze.
Thing to remember is that Bitcoin is an unregulated market, and you can bet your bottom dollar that their is hooky moneky business going on, on most of the big exchanges, especially those that deal with leverage. The market makers had the buying power, to liquidate the shorts, which pushed up the market way higher than it should have went, whilst the Market Makers sold their coins into the parabolic rise, and are now probably buying back now....or who knows, maybe they plan to be buy back lower still?
