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.

London financial expert, CEO of NEX Group, Michael Spencer, was among those financiers who consider Bitcoin a bubble. 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."
