Why It Matters
Improved, lower‑trust Bitcoin bridges could unlock the vast majority of BTC for DeFi, reshaping liquidity, borrowing costs, and revenue streams for the crypto ecosystem.
Key Takeaways
- •Less than 1% of Bitcoin supply is active in DeFi.
- •CeFi collapse shifted Bitcoin lending to decentralized protocols on other chains.
- •Most Bitcoin DeFi liquidity lives in wrapped BTC on Ethereum.
- •StarkWare and BitVM aim to reduce trust assumptions for Bitcoin bridging.
- •Higher yields require moving Bitcoin further from its native layer, increasing risk.
Summary
The video examines how Bitcoin can be utilized in decentralized finance, despite most BTC staying idle. It outlines the current state where under 1% of total supply is productive, and contrasts CeFi failures with emerging DeFi solutions.
Data points show a $1.3 trillion Bitcoin market cap but only $4.5 billion total value locked in Bitcoin‑related DeFi. Babylon staking holds $3.5 billion, Lightning about $300 million, while $7.7 billion of wrapped BTC sits on Ethereum. Borrowing markets on Aave, Morpho and Spark allow 70‑90% loan‑to‑value at 3‑7% rates; StarkNet incentives push rates lower, and sidechains like Rootstock offer higher rates with tighter LTVs. Yield options range from 0.4% native staking to ~9% on Stacks (paid in STX), with Ethereum‑wrapped yields near zero.
Eli Ben‑Sasson of StarkWare stresses Bitcoin’s need for scalability and expressibility, while Matt Luongo shares a personal non‑custodial loan using tBTC on Ethereum. The video also highlights Lightning’s $1 billion monthly volume in 2025 and 70% merchant‑adoption growth.
As trust‑less bridging technologies such as BitVM and ZK‑STARKs mature, more Bitcoin is likely to flow into DeFi, expanding liquidity and borrowing options while preserving Bitcoin’s security ethos. Investors and developers must balance higher yields against increased custody risk when choosing between native, wrapped, or sidechain solutions.
