interesting. Adding that experiments with the rewards is not new. It was the random rewards experiment before. It seems they keep experimenting until they find something that works best. I understand. Experiment and analyze is a scientific method that gives good results. I don't see how it could be done without using people in the experiment. We'll see how it goes.

I agree, it has the lottery style structure of the descending prize pool with the big prize at the top getting less and less as you go down the ranking. I immediately thought the same when I saw that. But there's also the competition element to it too.
