Isn't Sports Arbitrage dead?
There are a LOT of bookmakers around. And a lot of bookmakers means a lot of competition over the customers.
The bookmakers must have high odds to attract new customers. (This is why sports arbitrage works so well.)
You have discovered a way to change the game to your favor.
From now on, you will win.
Because bookmakers will continue to compete with each other to attract more customers, there will always be attractive odds.
Which means there will always be great possibilities for sports arbitrages.
By betting on two (or more) sufficiently high odds on different bookmakers, you can cover all outcomes of a match and be guaranteed to win.
You actually use the bookmakers odds against themselves. Sounds pretty good doesn’t it?
