Use ETH to buy tokens (Here we call it RUN). Sell tokens to get ETH when the price risen, or hold tokens to get dividends. Token price rises when buying, and goes down when selling. When buying, no handling fees. When selling, 10% ETH will be charged as dividends. This game runs round by round. Each round lasts 24 hours. If you want to get dividends, your total amount of buying tokens must be larger than your total amount of selling tokens in this round. It is held by a smart contract without human interfering at all. You can buy/sell tokens, or withdraw ETH at any time. Automatic pricing. Have fun!
