a bookie should be happy someone stakes big amount on their site and does it frequently; isn't it their main goal to bring traffic and volume?
The main goal of all the casino is entertain you and making money through the entertainment. If someone is arbitrage betting, he is winner all the time. That's why it's also called sure bet. They are beating the bookies with arbitrage betting. Most of the casinos don't allow arbitrage betting. In some cases, casino only limit the gambler so they can't anymore take the chance as with small amount of betting limit, they would make a very little amount which wouldn't worth the time.
It's sort of like a "hack" when an individual has infinite lives in the video game because he/she is NOT playing under the rules of the video game. It's simply an unfair advantage, plus it removes liquidity from the betting pool making it smaller, which might prevent the casino from accepting larger bets.
Arbers should use their strategies in Betting Exchanges because all of the bets are peer to peer. The exchange merely collects fees/doesn't have its own money in the liquidity pool.
I've known about arbitrage betting for quite a long time now, but I've never really come to understand completely how it's done, I've even heard and read post of some guys who end up getting restricted from accessing their accounts by some casinos on the charge that they were doing arbitrage betting.
Though like I said before, this is something Ive known I words for a very long time, but unfortunately, I've never picked the interest to want to really find out what exactly it is, how it's done and so on.
So, reading your analogy of having infinite lives in a video game, that tried a bit to explain it but it's not clear enough, so, if you don't mind, I honestly would appreciate a clear and precise explanation on how arbitrage betting is done, I know I could easily Google this, but we are here already, so, let this also serve as a contribution to the discussion.
Thanks for your anticipated time and effort.
