Show the community that you deserve to be a miner:
Tell us who you are, where you live, show us proof that you kick ass, or show us a picture of your gear, tell us your business plan, or impersonate Ken Code. Tell us what you plan to use all your mined BTS for. Be creative, or just be f'n cool, and make us laugh. Tell us who you know, drop some names. Have your famous friend sport a BitShares T-Shirt to the Grammys.
