I think a standard one-way virtual economy approach would be ideal for this: Track users’ “betting scores” separately from their karma, allow them to purchase score with karma, but not vice versa. Then lousy betters can blow their general reputation if they so choose, but a skilled better still needs to earn karma the “honest” way.
