BitMEX has an exciting new Factom futures contract which you can trade at up to 10x leverage.
BitMEX uses only bitcoin on their site, but the value of FCTBTC on Poloniex is used as the settlement for this new contract they created.
It's as simple as you deposit bitcoin, and use bitcoin to bet on the price of FCTBTC going up or down and then if FCT goes down you earn more bitcoin and if it goes up you can "long" the contract and earn money on it. This is a great positive development for FCT users.
Try them out, it's really easy to get started:
