While I do think this is surely good news for crypto, I think it still needs to go some lengths until it is ready for such mass adoption. It is pretty difficult in itself to explain to my parents what crypto is, let alone what a private key or a mnemonic seed does, and currently they are essential to know if one wants to use crypto. Of course, if any Mastercard terminal would accept crypto, that in itself would already solve some of these problems. Then we get to the (bigger) problem of actually convincing people why they would want to use crypto over the legacy systems in the first place. :D
