Here are the ways to set rewards in the Prediction Marketplace Development: 

• Offer badges or achievements for users who consistently make accurate predictions, encouraging pride in their contributions.

• Implement a points system that rewards users for accurate predictions, allowing them to exchange points for exclusive rewards, access, or services.

• Run prediction contests where the most accurate predictions win cash prizes or high-value items, motivating users to focus on quality.

• Provide tiered membership levels, where higher levels unlock better rewards based on prediction performance and reliability.

• Create a referral program that rewards users who bring in others, expanding the user base and increasing participation.
