Re: why CBOE and CME futures trading may LOWER / SLOW the price of bitcoin.
These futures contracts are the same as Gold futures contracts. First, its all paper and settled in dollars not BTC. More importantly, if you look at the Gold Futures market there are more Gold contracts than gold available: 542 contracts to 1 ounce of gold. 
The net effect is artificially keeping gold prices suppressed! If they overhaul that system and settle in real gold or mandate 1 contract per available ounce. gold price would skyrocket!
They are perpetrating the same scheme with BTC paper futures... the net result will like lower the institutional demand for BTC! Not the big upward pressure on price you would expect.
Here's Why the Gold and Silver Futures Market Is Like a Rigged Casino...

The only thing that will suppress the bitcoin price is the fact that the big institutional investors will buy btc futures,instead of buying bitcoins.This demand won`t help for increasing the bitcoin price.
I can`t agree completely with your theory about the futures contracts.I think that futures and all the other derivatives are like market gambling.One player bets for a higher asset price is the future,the other player bets for a lower price.It doesn`t matter that the futures contracts are more than the bitcoin mined.
It`s just gambling.
