Just a few thoughts of my own. It seems to me that BTC is starting to more and more follow the trend of the S&P macro movement swings. As traders become scared of the stability of the future, they reduce their investment purchases (or sell) across all their speculative assets. This global 'market fear and exhuberance' may end up impacting BTC as much as it does wall street, compounded by automated cross-market bot trading that occurs. (I tend to follow behavioral economics)
