One big difference is that if i send someone Crypto they can't spend any more than i have sent them. If i give them my credit card (and they possibly even leak/loose it) i have a far bigger risk for fraud.
In the U.K. with banks like monzo you can also raise/lower the limit instantly via an app. Also the fraud detection algorithms will automatically ask for 2FA on larger transactions or ones that look fraudulent e.t.c.
No not at all. No limits, actually only spending the exact amount with no way of spending more.
Yes there are modern banking solutions like this (we have instant transfers between banks with a comfortable QR scanning app just like google pay here in Switzerland) but this only works in Switzerland. For any international transfers we have to fall back to Swift transfers (slow) or credit cards (mentioned issue).
What kind of payment gateway are we even talking about? Are you describing "Sofort/Klarna"? I am not aware of any europe wide/international payment providers based on your bank account that does what you describe without basing on SWIFT and therefore being everything but realtime.
Well from the consumer side it seems to work pretty well, my bank (Monzo) has wise.com integration and it all works seamlessly.
But now we are specifically just talking about international payments where you explicitly don’t want any currency conversion or buyers protection, and the use case is just getting farcically narrow.
Or a credit card with spending limits?
