Bitcoin's strong performance in September is fueling optimism for a bullish fourth quarter in 2025, according to analysts. Institutional demand remains robust, with Bitcoin ETFs attracting $552.7 million in inflows. Analysts highlight a critical resistance level at $117,500, suggesting that surpassing this could propel Bitcoin to $124,000. The cryptocurrency has already reclaimed the $113,500 mark, and breaking through $117,200 is seen as vital for maintaining upward momentum. Current market conditions, including options expiry, may further support a bullish trend.
