The good thing is every day that passes, there's positive development regarding this, even crypto platforms and exchanges are contributing their own quota.
I remember seeing an article about how Bit get wallet are trying to create a wallet card that offers zero annual fees, good exchange rates etc, that provides users with a solution for global spending.
I know I've seen other examples like these, I just can't remember the exact brands working on them, but my point is we're getting very close to getting these solutions, which would hopefully facilitate widespread crypto adoption.
