This started out as a joke at work when a coworker pretended to make his own crypto-currency called "D Coin" and wanted us to try and guess a random number once a day until we "mined" one. Fed up after a few days of guessing, I noticed there was a website out there with a so called "D Coin" (http://www.dcoin.com.au/). So I grabbed the logo and "minted" the first real "D Coin". Now I just have to figure out what I can spend this on.
