Simple hodl them and wait the "revolution".
to hodl, you need to have bitcoins at first, and if you don't have any, then it is a problem
just buy bitcoin or two and gamble, if you're good gambler then you should win lots of bitcoins, and you're bad one then invest them, risky too but less risky than gambling
I disagree about buying a bitcoin and gamble.. that's not a good option...You will be wasting money if you were busted and gambling is too risky...Investments too have a risk.. we all know that some sites are ponzi, so better just go trading,atleast you are in control with your coins..
