I thought the same thing! 1 Million dollars worth of rewards, from 1 forecast! Biggest reward worth over $170K USD, yet the price of Wings either doesn't move or slightly down.

I guess the people earning rewards are happy with the amount of Wings they own, and the people who are buying and selling on exchanges are just day trading and not realizing they can use the wings to earn fantastic awards without risking losing their wings if their forecast is bad.
