What's the best way to monetize random niche subreddits?

I'm currently in a dilemma, people usually monetize Good niche subreddits, such as Ai, peptides, crypto, technology or financial related, but how can one monetize random niches, such as gaming, anime, or any random non main stream niches. Non mainstream niches won't have much opportunities in affiliate marketing and selling side bars and stuff, is making it another gambling, iptv hell hole the only way?

Nah, gambling/IPTV is not the only option Gaming and anime have loyal audiences, merch, digital products, sponsorships, and niche services can work too. It’s more about finding what the community actually wants
