The fast-moving, high-risk world of DeFi could soon give Bitcoin "HODLers" more ROI, according to new Binance research. Using Bitcoin, the largest and oldest cryptocurrency, on the DeFi protocol is a "massive untapped opportunity" that "has the potential to unlock billions of dormant BTC liquidity and improve Bitcoin's capital efficiency," according to a Binance report released Thursday. The report points out that only about 0.79% of bitcoin is currently used for DeFi.
