It's no wonder that Roobet is ranked 2nd because Roobet provides many new features and collaborations with several sports partners that make them get good marketing and continue to be active.
And roobet is also actively advertising on this Forum with Contests that I participate in every month etc.

And the Rollbit that I support at the moment is quite good with a 6th rank and still in the top 10, but this position will continue to change.

But I just found out about Yolo.com Casino, It seems that no one on this forum has promoted it, did I miss it?
But it's pretty great to be ranked 5th, outperforming Rollbit.
