That Stripe is involved is probably the best endorsement of Stripe being involved in crypto. Banking in South America is something crypto skeptics have heard for many years now. I was involved in a project that combined crypto with mesh networking. The launch was going to take place in South America. Why? Because university students in Brazil are desperate for a little bit of side hustle money, and incentives could cross borders easily using crypto. This was backed by first tier VC that had a number of crypto investments, including fundamental crypto technologies, alongside other more mundane things. Nobody involved in the project had any intention of creating a bunch of poor student bag holders. Nevertheless, the combination of mesh networking and crypto based incentivization wasn't enough to even turn it into the next Helium (they still around?)

SpaceX using crypto? Are any of their customers seriously going to pay using crypto? Are they gonna pay any of their bills using crypto? I'm not trying to piss in your Cheerios. But making real world use cases not die of uselessness is going to be a challenge.
