Players considering Stake most likely don't have Pinnacle as an option, or aren't considering them anyways.
In terms of KYC, I agree that Stake is better since Pinnacle has that requirement though I submitted my KYC there anyway since I was tempted by their odds which proved to be a good decision on my part in the long term.
I don't know why you've said their bonuses are worthless; sportsbet's 7% profit boost is nice, but Stake has bonuses in other forms that some players might prefer, like the VAR promo.
They are truly worthless since I don't see a point to these bonuses due to the live odds bugs. The odds fluctuate like crazy sometimes and I bet on very high odds due to these fluctuations sometimes.
