Is there a way to buy an option on bitcoin today the way I can buy options on a stock? Any recommended services / exchanges?

For pure leverage... Is there a recommended exchange that allows margin / leverage to buy bitcoins?

I'm new to bitcoin.

I found BitMex on Google. Not sure how good it is. Doesn't seem to support simple options which ideal for me.

My goal is either (1) buy an option or (2) to buy a few bitcoins on margin/leverage, and sit on them for a year or two. (Not day trade.)
