Nice idea on a game and website. Look nice and you have graphics for the ships and mining ore. Why do you not have corperations for players to join and invest their bitcoin into ? Ways for people to invest in the site ? I know that is not easy. Most that do are using a ponzi method. I know that is not what you want of course. If you have a working economy maybe it is possible ? The money players spend on the game is redistributed to investors and the rest is kept as profit for you. It would create much interest in the game.
