Bitcoin Climbs Ahead of Historically Strong October, But Warning Signs Persist – 29/9/2025
Bitcoin (BTC) is rising as October, historically its strongest month of the year, approaches. Ether (ETH) and all 18 other members of the CoinDesk 20 Index are also in positive territory, with the index up 3.0% over the past 24 hours.
Despite the gains, cautionary signals have emerged. Futures markets are showing a pullback from bullish sentiment, while options activity remains mixed.
U.S. exchange-traded funds are also seeing outflows. Both Bitcoin and Ether ETFs posted net withdrawals on Friday, marking the fifth consecutive day of outflows for ETH ETFs—the longest streak since September 8.
Another potential warning comes from the CME futures gap, the difference between Bitcoin’s Friday close and Sunday open. The gap currently sits below the spot price, and historically, these gaps tend to be filled, adding another layer of caution for investors.
