This is their theory for this particular decline because I have expanded in many previous posts, due to the launch of futures. Which are they surprisingly short trading at the early editions? Both CBO and CME have started Bitcoin futures during the last two weeks.
Although I am still fast on the bitcoin for a long time, and now there is no investment value for "moving forward from Wall Street" It has changed into a mantra in the Bitcoin Trading Class of 2017. In this way a great opportunity has been presented to engage in whatever is in this dip. It has been a long time before improving access to these devices for CBOE and CME futures.
