The Bitcoin War

I am looking to have a website made in which people fight, using bitcoin, to control a website. The initial bitcoin cost to control the website is 0.1 BTC, and when someone pays that amount, the cost goes up by 30%. If someone wants to take control over the initial buyer, they pay the increased amount and the first buyer receives 125% of his initial 0.1BTC, a 25% profit. Every subsequent cost is 30% higher than the previous one. This continues until no one buys for 24 hours, at which point the cost resets to 0.1, OR until a random reset happens, which should be programmed to be a 2% chance per transaction. The current controller of the website leaves a message along the top, typed in when they bought control. A similar website exists, for reference: [login to view URL]
