Personally I think betting exchanges had their days.
In the old days generally spoken the stupid guys were the gamblers and the smart guys the bookies. Now not every gambler is stupid and not every bookie is smart, but the general idea is that those paying the vig are behind and those receiving it are ahead. Then BetFair came initially making it look like as if gamblers were getting a better deal, since there would be plenty of new "bookies" that for some reason did not want to be bookie previously. Now these so called new "bookies" are slowly disappearing as they start to realise that the commission that BetFair is charging them is much higher than it initially appears to be. At the same time BetFair has educated the gamblers big time. The average Joe has become much more price sensitive and in his shopping efforts will have now discovered that BetFair often is simply not offering the best price anymore.
Am I alone in thinking this?
