Stake is amazing and just like everyone says it is definitely the best casino but "gambling sites" doesn't just involve casinos, there are other games as well. That is why there are other websites that are currently doing amazing in wagered numbers even compared to stake as well, not because stake is not good, stake is awesome but people want to play other games as well.

Look at nitrogensports for example dudes are leading the sportsbook world of crypto for years now and they do not really have any rivals, maybe when you look at the totals stake could be a better website but for someone who wants to bet on sports events there is no games available in stake, hence why they go to nitrogensports. There are other examples like this which is why even as the best casino stake still have rivals.
