$FF Layer 1 and DeFi are not mutually exclusive, as they are related and interdependent concepts in the cryptocurrency ecosystem. Layer 1 refers to the basic infrastructure of the blockchain (like Ethereum or Bitcoin), while DeFi (Decentralized Finance) are applications built on that infrastructure to offer financial services. The choice between investing in a Layer 1 cryptocurrency or a DeFi project depends on the investor's goals, as Layer 1 offers investment in infrastructure, while DeFi projects represent financial application and innovation.
