I expect to be able to short a futures contract because I know the price is going to go down.
Why would I want to buy GHS a month or two ahead of time knowing that the spot price is trending downwards all the time?
On a side note, if they allowed shorting I'm pretty sure it would be done to such an extent that there is no longer a price drop lol. Everyone would be so furiously borrowing the GHs to sell and thus creating artificial demand that the price wouldn't shift downwards as greatly. Anyways, I agree that having futures contract without short-selling is rather deceptive of them - basically their expecting everyone to speculate and probably take a loss to line their pockets.
