So it means that they are prepared for almost everything, they took the control of almost all the scenarios to make sure that they will never lose money, that's great! For them of course.
Trading halts might temporarily reduce volatility, but that would only be true if the underlying spot market followed the CBOE futures market. By all observations, it appears to be the reverse: the futures market follows the spot market, with minor exceptions.
Are there "real" people putting money on those futures? or at least, people with a tiny knowledge about investments?
Yeah, I believe both institutional firms/hedge funds and Main Street investors have access to the market, as it's available through most major broker-dealers. In general, I would guess that the people trading regulated futures generally understand markets and may be hedging operational exposure (i.e. not trading to profit but to hedge). Whether they understand Bitcoin is another matter entirely....
