CBOE futures started trading last night December 10, 2017. The CME Group futures will start trading on December 18, 2017. The CBOE futures acts as a mini futures contract since its contract value is 1 Bitcoin while the CME Group will be 5 Bitcoins.
We discuss this in the video below and a potential trade. I actually started placing limit orders at the bid when the market moved above 18,000 area but did not get filled. Looking for a second leg up to 20,000 but will probably sit this move out.
