The emergence of the Bitcoin DeFi (BTCFi) ecosystem is a significant development in the world of cryptocurrency. BTCFi refers to financial applications that utilize Bitcoin as collateral, settlement asset, yield source, or security layer without altering its base chain into a general-purpose smart contract platform.
BTCFi aims to make Bitcoin more productive by providing lending, borrowing, staking, and yield opportunities through sidechains, Layer 2 networks, bridges, and other technologies. This approach leverages the unmatched liquidity and monetary credibility of Bitcoin, creating a large market opportunity.
However, BTCFi also introduces risks such as bridge risk, smart contract risk, custody risk, and user misunderstanding. To mitigate these risks, it is essential to separate savings Bitcoin from active Bitcoin, with cold storage remaining the low-risk core while only a smaller portion enters BTCFi strategies.
