Two classes IMO

1. AI Agents: Varying use cases 
ie: AIXBT- Specializing in market insights, it uses cutting-edge algorithms to analyze real-time data streams, uncovering narratives, trends, and actionable signals
CoqAi: Advanced Meme Generation
But ultimately they create tons of engagement and capture attention when attention is everything in crypto.

2. AI Infrastructure: creates the tools and foundation for launching agents and other digital economies powered by AI @virtuals_io @delaunch Bitensor

I would also further distinguish Memecoins, Community coins, and Shitcoins

Memecoins: They often group shitcoins as memecoins but meme coins should be specifically for long standing internet memes like PEPE and DOGE. They should strategically do nothing, pure meme. 

Community Coins: COQ MOG SPX6900 

Shitcoins: 99% of the pump fun coins the past year. Controlled supply nonsense
