The fact that people around the world are trading hundreds of billions of dollars of stable coins [1], with India, Pakistan, the Philippines and Brazil in the top five countries [2], not least of all for the purpose of "greater monetary stability" [3], I think points toward the revolutionary usefulness of its inherently non-speculative properties (as referenced in positive applications of crypto in above comments).
It really has been a shitshow of get rich schemes, and yet crypto keeps not dying, instead increasingly getting applied to extremely valuable real world every day use cases, which I think is evidence of the value of the inherent technology.
