The common ground of most metas we've seen over the years is that they come with the simple promise that you can "make it" from zero. Memecoins, InfoFi, even NFTs were so attractive to new entrants because they had this (often unrealistic) promise of quick profits. So when you're thinking about what's next, look for things that have this element to them

It can come in different forms, for memecoins it was clearly the "find a 1,000x" gamble, for InfoFi it's the content grind

In all of them, it is the people at the top of the narratives who benefit the most. Sometimes more, sometimes less extractive
