I know I'm not the most technological fella on the planet, but had I known we can create our own currency I would have been all over that.  Imagine starting off with however much you want and that people would accept it.  I'm sure its not that easy, but between bitcoin (still have no idea how it works) to the new Dogecoin (which started as a parody of bitcoin but may now be real) who knows what we can use to pay for things.  I'm sure the power company and the bank won't take them, but one guy is selling his house in exchange for Dogecoins.  Not sure how this works, but if it does expect "DaveBits" to be on the market shortly.  Find out more about buying a house for Dogecoins here.
