The one nice thing about crypto is that it's decentralized to a point in which, if banks and card processors won't do business with you, you can use crypto.

Gab for example. You can't purchase gab pro with a credit or debit card / banks.

Need to send cash, check, or crypto.

So crypto is good for digital payments when banks won't allow themselves to be used.

This goes for many businesses that the rich and powerful dislike, such as Kratom sales.

Kratom isn't illegal in 95% of America, and it hasn't been shown to be very dangerous in moderation to most, but big Pharma and others are pissed, because millions of Americans have cut their dependence on expensive pills, and replaced it with a natural and dirt cheap plant that isn't monopolized.

So that's where I think crypto has a purpose.
