You can find sites that show you sure bets. When I did arbitrage betting in the past (...)
Why did you stop? Did you get banned or was it just not worth the time?
Yeah, I think the most arbitrage opportunities nowadays would have a profit rate in a range of 1%. One could think it's still great since it's a guarantee, but things are not so rosy when you consider that to win a lousy $100 you'd have to put in $10k. And since a lot of the gambling sites are registered in some exotic jurisdictions, if one of them decides to freeze your funds for "suspicious" activity, there's not much you can do legally. So the risk is still there.
