Okay, so you like to stay on top of the most current technology? You like to be on the cutting edge? Well how about getting your hands on the future of global commerce itself! 

Some economists are predicting that Bitcoin will be that future.

Don't know what a Bitcoin is? We'll tell you! Bitcoins are a virtual currency that allows for transactions between merchants, private citizens and enterprises without the need for pesky intermediaries like banks or financial institutions.

Which means: the value of Bitcoins are not tied to any currency or subject to financial regulation, as of now. Bitcoins are stored in a digital wallet which is either located on a personal computer or in the cloud.

The advantages of using Bitcoin are: 1) almost zero processing fee, 2) global coverage, 3) direct/instant party-to-party transactions, and 4) the value of Bitcoin is decentralized and not controlled by any one institution so is not dependent on some monetary policy.

And right now, one Bitcoin is worth about $235.50 USD. So there you go.

And plenty of online marketplaces (and real world ones, too) accept them as payment. Take a look: http://www.coindesk.com/information/what-can-you-buy-with-bitcoins/
