I'm sorry for not being clear.  My point was that if I have any non-obvious insight into how Fed policy will shape the future, I can already make a billion dollar bet in other markets.  I don't think it's realistic to expect Truthcoin to do anything but aggregate obvious insights regarding future events that bettors can elsewhere gain as much exposure as they want to.

The only markets on InTrade that received any volume were the election markets.  There wasn't any other simple way for a bettor to gain exposure to those events.  InTrade got shut down for pissing off the CFTC by offering prediction markets on the price of commodities.  Those markets received no volume.
