This is a common challenge for many platform owners because it can affect market growth. If you don't regularly improve your platform or offer incentives to your users, engagement can start to decline over time.

You can also encourage activity by offering rewards, referral programs, or community incentives for active participation. 

Simplifying the user experience, improving onboarding, and sending timely notifications can help users stay engaged and return to the platform more often. 

When users clearly understand how markets work, how outcomes are verified, and how rewards are distributed, they are more likely to participate regularly. 

If you follow these strategies, your prediction marketplace platform is more likely to grow and perform better.
