Total prize pool per day is:
1440 coins for publishers
720 coins for self-miners on the platform
This is divided up between all users who send traffic or use the mining platform. We use a custom algorithm on the publisher side which takes into account unique visitors and hashes so it is not directly correlated to hashes found or blocks mined.
Laineux we keep CPU usage lower than our competitors to ensure user experience on the website is not affected.
