Bitcoin Climbs as October Approaches, But Caution Signals Emerge – 29/9/2025
Bitcoin (BTC) is trending higher as October, historically its strongest month of the year, nears. Ether (ETH) and all 18 other members of the CoinDesk 20 Index are also in the green, with the index up 3.0% over the past 24 hours.
However, several warning signs suggest traders should remain cautious. Futures markets are showing a pullback from bullish positions, while options activity continues to send mixed signals.
Exchange-traded funds are seeing outflows, with both U.S. spot Bitcoin ETFs and Ether ETFs recording net withdrawals on Friday. ETH ETFs in particular posted their fifth consecutive day of outflows—the longest streak since September 8.
Additionally, the CME futures gap—the difference between Bitcoin’s closing price on Friday and its opening price on Sunday—remains below current spot levels. Historically, these gaps are often filled, adding another layer of caution for investors.
