The 90-day rolling volatility of BlackRock's Bitcoin ETF, IBIT, is decreasing, nearing a historic low, according to Bloomberg's senior ETF analyst Eric Balchunas. This reduction in volatility aligns with Bitcoin's rising prices, making the ETF more appealing to large investors seeking digital gold rather than technology stocks. Consequently, IBIT's fund flow capture has significantly surpassed the average level over the past six weeks, indicating increased investor interest.
