I'm not guaranteeing that a steak can never scam. But I think they won't scam easily because they have already spent millions of dollars through various marketing partnerships and giveaways and continue to do so and they are one of the biggest casino sites in the cryptocasino world .so i believe that they can do real business without scamming.
I think so too. If they want to cheat their many members, they will not last this long and can compete with other trusted and top casinos. Maybe they will end up losing the trust of their members so it won't take long to see them disappear from the list of trusted crypto casinos. Doing multimillion dollar promotions and doing it continuously provides an opportunity for them to gain more trust from the members so that they can play there comfortably and safely.
Yes there are many trusted casino sites in the market competing with Stake and if Stake accidentally makes a wrong decision it will become a weak point for them and the sites behind them will overtake them. I don't think the steaks would go that far and put themselves in danger .
