I don't really agree. I think it is much more fun that you can also win some real crypto while you are on rank 1. Ok, the chances are maybe limited but it is more exciting than just winning Funfury. Maybe with a lot of luck (and a good strategy), you can reach the top 50, but even then the reward you will win is still quite small.
I have noticed that if I really put time on this game, I can improve my position in the leaderboard.
So yes, strategy and your allotted time is important if you want to be included in the top 50 to get the reward.
But if you are already in the top 11-50, is your time worth to get such very low reward?
Maybe if you have all the time in the world to play, this is nice. But if you have other job, I think, you are wasting your time.
