Checked your site out after a while op and it's crazy seeing scam sites like Fortunejack and Nitrobetting getting such high ratings while Polymarket just got a C. Make it make sense. FJ and Nitrobetting were decent before, but not anymore.
Polymarket deserves a B at the very least. Sites like BTCGosu etc are doing a better job in comparison.
We typically add new gaming brands to our site with a rating of "C," and then review and adjust the rating based on various factors. Therefore, it's possible that Polymarket's rating will soon be raised to "B." As for FJ and Nitrobetting, they're still holding their own in our rankings due to their previous performance history, but have gradually lost ground over time.
