Betting regularly with the P2P Betting Bot on the World Cup. So far so good (and a bit of extra GBYTEs).
The only thing I would work on for the future is the possibility of placing multiple bets instead of singles. (parlays

)
But that's good for now
Do you have any idea who is actually posting those odds? I can't tell whether people are actually betting against each other or if there is a well capitalised bookie that set's the lines.
