Bitcoin exchange-traded funds (ETFs) in the United States see their worst month since they began trading in January 2024, according to reports from Free Malaysia Today and Moneyweb. Both outlets say June generates net outflows of roughly US$4 billion to US$4.1 billion across 13 listed bitcoin ETF funds. The figures represent the largest monthly net withdrawal since the ETFs launched, indicating broad investor selling or reduced demand during the period. The coverage is consistent on the overall magnitude of the outflows and the timeframe, with both articles pointing to June as the weakest month to date for the group of funds. Neither source attributes the outflows to a specific cause in the provided text. Together, the reports emphasize that the cumulative net outflow in June marks a clear break from earlier months, when the ETFs had not recorded a larger net negative flow since their introduction at the start of 2024.
