Bitcoin DeFi has been a dream for bitcoiners and for the crypto industry in general. Bitcoin is the most liquid, familiar, and decentralized cryptocurrency in the world. Although there are multiple pathways to bring Bitcoin into the DeFi realm, bringing Bitcoin into the Ethereum ecosystem seems like the easiest approach at the moment. Ethereum has been the home for all the major DeFi protocols; MakerDAO, Compound, and Uniswap. Using BTC within these protocols instantaneously brings more liquidity and opens the door for multiple use cases.
