I'd like to ask OP did you compiled all these groups or if you just downloaded them from other sources, It's not easy to compile all these links it will take you several days to over a week It's indeed a comprehensive link.
Have you promoted casinos from these groups and platforms how's the result of your promotion and how did you come out with a specific amount?

I still maintain that influencers, Bitcointalk, and review sites are the best platforms for casinos to launch their marketing, they can add more coming from this spreadsheet if casinos want to add more
