Hmm right. What do you reckon is the rationale behind crypto debit cards? For example, coinbase probably wouldn't launch such a thing if there wasn't a large enough user base for it, or not?
I'm sure there are a decent amount of spenders out there. By this point there'll be a lot of people sitting on free money. Spending free money feels jolly nice.
It's not the driver or cornerstone of this whole thing though, it's a byproduct of a reasonable size. And for some it may be the only significant amount of money they have so they may have no alternative but to liquidate some.
