More importantly however, whatever you think the reason for this is, please look at nakowa's yesterday winning charts and tell me that there is no "exploitable" pattern to it:
That's all easy with hindsight. The hard part is being sure of the exploitable pattern of Nakowa's next run.
Similarly, I've noticed BTC trading in the 130-145 range over the last weeks. What's stopping you from selling at say 142 and buying back at 135 repeatedly? Would have been a winning strategy over the last weeks/months. What could possibly go wrong...
