Bitcoin recovered to $84,000 on Wednesday after rising around 2.5%, supported by renewed ETF inflows and slower profit-taking. U.S. spot Bitcoin ETFs received almost $653 million in net inflows on October 19, ending a week of outflows. However, the funds' 30-day average trading volume remains below a quarter of the year-earlier level. The Federal Reserve's October 28 interest rate decision could test the recovery because higher borrowing costs could pressure cryptocurrencies. MSCI's forthcoming classification changes also raise concerns about potential index-related selling, with Strategy and Metaplanet flagged in an earlier test.
