NFTs have a universal video reward cap per day called Watches. The current reward viewing cap is 5 videos per day per NERD NFT activation. This limit resets back to 5 every day at 12:00am UTC.
You are allowed to activate up to 5 Nerds per day, and each time you activate a new nerd, the watch daily limit resets to 5. Therefore, the total number of videos that can be watched is 25.
