Cryptocurrency has existed for over 15 years, and many people's true feelings are: this industry has not brought much useful stuff. People trade Memecoins not because they love funny patterns, but because this industry has not produced any truly attractive user applications.
Think about it, those L2 or L1 projects that launched in the past few years, if they have not gained even a bit of user or product-market fit (PMF) to this day, yet their tokens can trade at a market value of several billion dollars and still talk about 'the future of finance' at conferences, users will naturally be angry—especially after they have lost a lot of money. Such things are an inevitable reaction of the market after a long period without results.
