Not saying crypto has failed in all aspects, just in the use case talked about in the blog post. I don't see crypto competing with e.g. Nequi any time soon.

The project you mentioned is interesting, but I see it as something much more for the middle and upper classes. I know plenty of crypto enthusiast in those circles.

I tried Buda, which is mentioned in the article as partner. It has been the most tedious experience with a "financial" product I had in my whole life.
