From my experience, it depends on how easy the integration is. Nobody wants to wrestle with clunky code just to add a “cool” option. I came across Inqud’s API integration https://inqud.com/integration-api which basically lets you plug in crypto payments without reinventing the wheel.
That kind of solution makes it less about “hype” and more about convenience. Customers get extra ways to pay, businesses don’t bleed on hidden fees, and developers don’t waste weekends debugging spaghetti code. It turns out it’s more practical than it looks from the outside.
