I will not give examples of coins that could potentially grow and be in demand, but it seems to me that these would be ecosystem projects that would connect different blockchains with each other and private coins, as the world becomes more financially controlled, the owners of anonymous coins like Monero could remain in the shadows.
Agree... Adult Content Business is the next to empower the blockchain ecosystem together with the betting business its always win win ...
Both Business niches are still not heavy utilizing crypto and have billions in revenue every year.
So Porn projects and Betting projects with utility is the next gem from my point of view.
