Hello, I have an idea for a web based game: a site that lets you predict the future price of a stock or commodity. On registration with your phone, you'll be given 10,000 virtual dollars to speculate with. You'll be shown a list of hot stocks or commodities like GOOG, AAPL, crude oil, Euros, and be asked to guess what the price will be tomorrow, a week from now, a month from now, etc, and wager a certain amount on your guess. Every day, for each security, prices will be recorded and used to redistribute the wagered funds among all the speculators for that day. If your guess is close, you'll get more than what you wagered, and if it's not, you get less or nothing. If you run out of funds, you pay $10 for another 10,000 virtual dollars. There would be a player ranking system and players will play to improve their ranks. Top players will be honored every week. For each future security, we could use a weighted average of guesses so far to predict what the price would be on a particular day. We would keep track of the eventual accuracy of those estimates, too. Would you play such a game? Would the predictions be accurate? Thanks.
