It is very simple to understand obviously, if there is no one predict 100%, the 1M prizepool will go no where as there is a fixed 50k prize for that possible situation. The 1M prizepool is designed to those who can predict all correctly, there is no reason to distribute it if there is no one make 100% correct prediction. It is a contest and the contest has its own rules, 1M dollars is not a small thing that's why it is designed for a hard thing. All in all it is about business not about charity. The requirement to participate is very simple, and I'm sure no site will distribute 1M dollars for such easy requirement.
Right. That's why there is a $50,000 fixed prize. If no one can predict all the matches correctly, Then the most correctly predicted participant will be on the top and he will get a bigger percentage of the prize pool. 1M dollars is not a small amount to be distributed. Even I am not sure if casinos can earn 1M dollar during the contest. But, It's possible when it comes to Duelbits, But there are a lot of casinos and 1M dollars is not even their monthly profit.
