You bought futures for a coin that will never exist. Good luck with that! That's why you just buy coins that exist! I thought that went without saying, but hitbtc is sketchy and they love to pull this crap.
I doubt he bought any actual futures contracts, but yeah, that's what he essentially did. And when you trade "futures" of yet-to-be-created coins like some of these exchanges love doing lately, you're literally speculating on the possible price of something that may or may not happen.
Am sorry to hear of your situation, but at the same time hope that you have learnt your lesson.
Oh and yes, S2x was suspended... but some miners decided to fork anyway (block height 494,784). Happened on Nov 17, something like 5% miner support, last I heard anyway. Can't be bothered to see if the chain survived or not.
