[Analyst: The abnormal flow of spot Bitcoin ETFs seems to be affected by investors' uncertainty about the path of the Fed's rate hikes] Golden Finance reported that BTC Markets cryptocurrency analyst Rachael Lucas said that the abnormal flow of spot Bitcoin ETFs seems to be affected by investors' uncertainty about the path of the Fed's rate hikes, especially when the United States is expected to release a major economic report on May 31. If US inflation data exceeds expectations and personal income and spending trends rise, it may curb investors' optimism that the Fed may cut interest rates in September. A more hawkish Fed may have a negative impact on demand for risky assets, including Bitcoin and related ETFs.
