Bitcoin Fi just got a major upgrade. Picture this: lock your BTC, borrow MUSD at a fixed 1% rate—no rate shock surprises. That's the foundation. Then comes the practical layer—a Bankcard that actually lets you spend that MUSD on real consumer goods, not just trade it away. And here's the kicker: the protocol is rolling out aggressive incentives to pull every Bitcoin enthusiast into this ecosystem. More actions, more rewards. It's designed to make holding and using BTC on this L2 solution feel natural, almost effortless. This is what a purpose-built Bitcoin Layer 2 looks like when builders actually think about usability.
