Nexo, a crypto lender, has teamed up with global payments company Mastercard to launch the world’s first ‘crypto-backed’ payment card. This signals the latest move by crypto and incumbent financial networks to join forces as digital assets become more mainstream. Nexo said that the card, which will be made available in some European countries to begin with, will allow users to spend without having to sell their digital assets, such as Bitcoin, which are used as collateral to back the credit granted, NDTV reported.
