Arbitrage betting is forbiden on casinos, they consider it as an abuse, and I don’t know how but they will know if you are doing it with multiple casinos, so, users must be careful about this linda of practices because just as op mention they will close your account and keep your money of you they it.
It is not "forbidden on caisnos" it is not allowed on a VERY SMALL percentage of sketchy ass scammy crypto casinos.
97% of the sites I've used in my lifetime paid me out no issues and have nothing about not allowed arbitrage or sportsbook advantage play in their terms of service.
and I am a longterm advantage player doing this for a living, I have easily played at 200+ different betting sites.
It is the small minority of terribly ran greedy casinos:
betpanda, sportbet.one, WE88 and rainbet from the top of my head.
That have forced this narrative on people of this forum that it's somehow in their right to take winnings from players under the guise of "arbitrage betting".
Now this next point is VERY IMPORTANT to everyone, so PLEASE READ THIS CAREFULLY:
Casinos will NEVER EVER be able to know if someone is arbitrage betting.
In order for them to know if you are arbitrage betting, they need to have the other side of your bets which would be placed at a completely different casino (and different oddset/odds provider)
So unless the same parent company owns two casinos, and they are communicating with each other (very rare situation) it's just not possible for them to know.
This is CRUCIAL to understand, because lots of people on this forum: holydarkness I'M SPEAKING TO YOU HERE. Believe that arbitrage is somehow poossible on a single set of odds, it is not.
These bookies also do not allow valuebetting or anything that would put the customer in an advantage over the casino.
This is completely insane considering valuebetting is just having a better opinion on the probability of an outcome occurring.
If I think the Golden State Warriors should be favourites against their opponent from some basic analysis, form and lineup news, but the bookmaker disagrees.
Then over a big sample I am correct more than them, I am now a sharp and a value bettor. Sites like betpanda would literally confiscate your funds for using your brain in this way.
You just have to avoid these terrible businesses and do research before signing up, stick to the legit sites that have been reputable for a long time in this space.
