The virtual currency bitcoin, created in 2009 by the anonymous hacker “Satoshi Nakamoto,” has been making lots of headlines lately. The value of a single bitcoin, created through a complicated computer software process, has shot up to $844 from less than $15 at the beginning of the year. But bitcoin is hardly the only non-traditional means of exchanging value. There are competing digital cash wads and even some ordinary household items that can be used as money.
