So basically it would be a sport pool (whichever sport) where you put *dynamic* bets -meaning you can change your "bets" along the way by buying or selling a team asset, and the value of that bet change depending on the valuation of each team, or what the people think the odds are-
Wow, that's interesting!!
You could hold and hope your team win, or trade actively for each game along the way...
But what happens with the assets of each team when the season is done? Would something like the PTS dump after a snapshot would happen, so holding too long on a winning team wouldn't be that good since everybody gets out when the season is done?
I've thought about this some. They ran a World Cup betting pool (Germany really came through for me!) over on NHZ and it got me thinking that you could probably do sports betting pools almost totally autonomously, probably even without feeds (though you'd need to put some thought into preventing manipulation).
So suppose we've got two teams: the Satoshis and the Larimers, and they're competing for the championship. I could go into the Sports Betting DAC and create a betting pool for this championship, which would be composed of two assets: SATOSHI and LARIMER. Unlike an ordinary asset creation, the DAC controls 100% of the shares of these assets, and puts them up for sale on the open market. Bettors come in and buy shares of either SATOSHI or LARIMER, and the DAC puts all the bets in a common pool. If the Larimers win, the DAC pays out the pool proportionally to holders of the LARIMER asset, and since the game is over, all SATOSHIs and LARIMERs vanish because we don't need them any more.
Here is the fun part: The more shares people purchase, the higher the price of the next share goes. There is a lot of design leeway here; I have no idea what the best price growth curve would look like. Would buying a LARIMER increase the price of a SATOSHI? (I think not, but haven't thought through it all the way). Should the price increase be linear? superlinear? Should it have a time-varying component? All good questions. The upshot of letting shares increase in price over time is that there should be a mad rush at the beginning to buy shares since people know they will get more expensive as time goes on.
I said above that this shouldn't require a feed: The trick to this is you
never close betting. Betting stays open throughout the game and even afterwards. How will the DAC know which team won? Well, if people bought more LARIMERs than SATOSHIs, then the Larimers must have won. If the pool is large enough, it would take a huge whale to buy so many of the "wrong" team asset that the DAC would conclude it had won. You'd have to design some clever way for the DAC to "know" that it should shut the pool down and make payouts; maybe you could measure average market activity and make payouts when the moving average share transaction volume has dropped below some threshold.
