Historically, September has been a difficult month for Bitcoin, often referred to as “Red September” due to the historical trend of negative performance.
Changing crypto paradigms
However, market analysts suggest that 2025 could defy this trend. Increasing adoption by institutional investors, fuelled by the success of Bitcoin ETFs that have absorbed significant capital, and the continued shortage of supply post-halving are creating a new dynamic. These factors counterbalance historical volatility and could lead to a more favourable outcome for the leading cryptocurrency.
In addition, there is a notable shift in investor behaviour, with a steady rotation of capital from Bitcoin to Ethereum as investors seek riskier assets in anticipation of a potential “altseason” Data from various sources suggests that Ethereum ETPs are seeing significantly larger inflows than their Bitcoin counterparts.
This shift, combined with a potential easing of monetary policy by the U.S. Federal Reserve, could set the stage for a broader crypto market rally.
Cryptocurrency market on the move
While technical indicators still show some downward pressure, the fundamental support from institutional and corporate players, along with optimistic macroeconomic forecasts, paints a more complex picture than previous Septembers.
The latest analysis of Bitcoin price by Coinidol.com shows that BTC has fallen, but has remained above $108,000 since August 29. It will resume its positive momentum once it breaks the $112,000 level and rises above the moving average lines. Currently, BTC price is fluctuating around $110,200.
This year’s market dynamics suggest a maturing ecosystem where traditional cyclical patterns are being disrupted by growing institutional interest and a diversifying investor base. The narrative is shifting from a simple historical trend to a more nuanced view that takes into account the significant structural changes within the crypto market.
