Why do you void arbitrage winnings? You don't allow arbitrage on your site? Do you mean he bet on double side to decrease the risk? IMO it is acceptable.
Hi jujugoboom, I think you confuse arbitrage betting with "matched betting". An arbitrator bets on double "sites" and he "doesn't decrease risk", he takes none. No matter the match result, he will always have a small gain. Different sportsbooks have different policies about arbitrage, we are against it.
Mate, I didn't even do this. I just bet on powerbet.io for the games it had best odds. That is all I was doing.
I keep searching for bookies with best odds on the game I want to place bet.
