You are kinda right though the player did win the huge amount through Sportsbet.io and didn't have any issues with receiving his winnings which is why they definitely deserve partial credit in this case.
Their director also invited him to their HQ to treat him exclusively which is a good gesture from their side.
That must've been a really awesome experience being treated by the director of the Sportsbet and it's on the HQ because there's no way that something like that is going to happen to anyone plus the wins is something that will definitely change this man's life. He's also going to be the face of Sportsbet for awhile because of his win and I'm sure that whatever Sportsbet is investing in this guy aside from the wins is definitely going to be a big return for Sportsbet because they've made him a VIP and given the appropriate treatment. Sportsbet will be a really good place to invest if it ever goes public as a company.
