Bitcoin's real power isn't about being rebuilt from scratch—it's about unlocking what's already there. The shift toward making idle BTC productive is reshaping how we think about the oldest cryptocurrency in the space. Instead of sitting dormant, capital can now be channeled into yield mechanisms and made programmable across different protocols and applications. That's what BTCFi in practice really means—taking dormant value and turning it into dynamic, composable financial infrastructure. The ecosystem is proving that Bitcoin doesn't need reinvention; it needs activation.
