Bitcoin experienced a significant decline, dropping between 5% and 10% intraday, as global markets shifted to a risk-off sentiment. This downturn is attributed to rising US Treasury yields and a cooling appetite for riskier assets. In a notable development, Vanguard has announced plans to open access to regulated cryptocurrency ETFs for approximately 50 million clients, significantly broadening mainstream exposure to digital assets. Currently, spot Bitcoin ETFs manage around $120 billion in assets, while Ethereum ETFs are nearing $20 billion. This expansion comes as markets await key core PCE inflation data, which could impact Federal Reserve policy and the dollar's direction.
