It's also a heck of a lot quicker to process, (effectively instant) and works even on holidays.
And of course, banks like Bank of America, Capital One, and tons of other financial institutions simply refuse to use it, because that would mean spending money on changing their infrastructure, and making it more convenient for people to also use accounts outside of theirs.
Seriously, it's been ages, and they've refused to use it at all, even though it's purely a financial and technical upside for every user once it's implemented.
Mullvad actually does this for their VPN service, which I think is great. For a VPN company that doesn't want to store identifiers about you, taking crypto makes sense because that also doesn't necessarily have identifiers about you attached that they could read or be required to store, unlike a card that requires your name, address, and card number.
Other than that though, no larger companies are going to do anything of the sort, let alone be likely to even implement it as a payment method to begin with. Tons of additional technical complexity for little to no benefit.
