Every crypto enthusiast has definitely come across XX-fi projects, but whether it's SocialFi, GameFi, or other fi, they all ultimately end up resembling a pyramid scheme—using later entrants' funds to incentivize early participants.

What is the core issue behind this? Essentially, if there’s no incentive, no one would play this game; if there’s no expectation, no one would post content on this platform.
Prediction markets themselves also fit the definition of XX-fi: traditional scenarios combined with economic models. That is, Event-Fi (Event Finance) / Truth-Fi (Truth Finance), where people directly use real money to vote on their stance.
But the emergence of prediction markets has truly lowered the barrier for other XX-fi projects:
Major real-world events -> generate huge controversy -> prediction market opens -> global capital floods in for betting -> odds data becomes news material -> media reports again -> attracting more outside capital.
This creates an almost zero-cost customer acquisition loop, with genuine user demand. I believe this is what allows projects that combine traditional scenarios and finance perfectly after introducing the XX-fi concept.
