I also got limited years ago. You can see it once your "max bet button" disappears.
After that I can bet like 10$ on singles on basketball where I could bet an easy 1k before.
When I asked my host back then he just told me its the odds providers decision, because I won too much. Same old.
They want suckers that play casino but once you have an edge on sports they show you the door. Today I got 0.08$ weekly bonus for platinum 2 account, thank you stake.
So your max bet on sports is just $10 now? so I was wondering if there could be a gambler who always wins on every bet or at least 9 wins in 10 bets?
If there is I am willing to buy a betting package or even share profits with them, honestly I don't believe in stories like this unless they have a team that can manage the final result.
