All Bitcoin traders should note two important dates in their calendars: December 10 and December 18. It is these days that the CBOE and CME group will begin trading in Bitcoins futures and options. Later, other traditional exchanges can join them. At the same time, not all traders understand that these events mean for the community and how the situation in the last two weeks of 2017 can change. The market of trade Bitcoin can be compared with the river. Its flow depends on constant quantities, and therefore it usually flows in one direction. On the other hand, the Bitcoin futures market is similar to the ocean with thermohaline circulation: its flow depends on several variables. Sharks of the futures market are not friendly at all - they will do everything to earn money, even if they have to go through the heads of other market participants.

Nevertheless, he believes that the price of Bitcoin will reach $ 20,000, and only after that, it will sharply go down. In an interview with Guy Johnson on Bloomberg TV in London, Spencer said he had no idea if the Bitcoin price would double before it halved, but noted that the $ 20,000 level could be reached "damn fast." Johnson called the growth of Bitcoin, which exceeded the $ 11,000 mark last Wednesday, "irrational."

Despite the expectations of the "collapse of the bubble," which is intensified due to the fact that Bitcoin with whistling passes all the new frontiers, every new level is given to it more easily and almost without serious corrections. On the morning of December 6, another price level of $ 12,000 was passed, at which the price did not stop and moved on, approaching $ 12,500, and the GDAX exchange went up to $ 12,540.
