A new study challenges the long-held belief in a consistent “September Slump” in cryptocurrency. This recent research reveals that factors like institutional investments and regulatory signals significantly influence market trends, rather than seasonal fluctuations. 2025 data indicates this shift is driven by increased institutional flows, notably from Grayscale and BlackRock’s spot BTC ETFs, which have fueled robust inflows exceeding $55 billion in Q3 2025. This contrasts with the historical perception of a weakening market during September. The influx of capital into Bitcoin, combined with stablecoin reserves at around $300 billion, underscores an optimistic outlook for market stability.
