I run/ran a website where you could shop on AliExpress using crypto and advertised it as the only legitimate crypto website around. I had universally positive reviews but made low 5 figures in profit over the course of ~4y (not terrible as passive income considering the operating costs were nearly zero) before the latest crash dropped usage to nothing and I let bit rot take over.

Unfortunately the vast majority of crypto adopters are just riding the bubble for investment and have no interest in any other use cases, which are admittedly limited.
