The cryptocurrency market faced widespread declines on September 1, 2025, as multiple factors combined to create selling pressure across digital assets. The total crypto market capitalization dropped $44 billion in 24 hours, falling to $3.76 trillion.

Bitcoin led the decline, trading at $107,478 after breaking below the critical $108,000 support level. The world’s largest cryptocurrency hit a two-month low, declining from $112,500 over the past week. Ethereum and other major altcoins also posted losses between 1-3% during the same period.

Bitcoin (BTC) Price

A major whale transaction amplified the market downturn when a large holder sold 24,000 Bitcoin worth approximately $2.7 billion. This massive sell-off triggered around $900 million in forced liquidations across the market. The whale activity created sharp price drops and increased volatility for multiple cryptocurrencies.

The timing of the whale sale coincided with the expiry of $13.8 billion in Bitcoin options contracts. Options expiry events typically create uncertainty in the market as traders reposition their portfolios. The combination of whale selling and options volatility intensified price swings throughout the day.

September Seasonal Weakness

September has historically been a challenging month for cryptocurrency markets. Bitcoin has closed lower in eight of the last ten September periods, creating what traders call “Red September.” This seasonal pattern reflects investor psychology and typical liquidity cycles in digital asset markets.

September has historically been Bitcoin’s weakest month.

Portfolio rebalancing activities typically increase during September as institutional investors adjust their holdings. Tax-loss harvesting also contributes to selling pressure as investors lock in losses for tax purposes. These factors mirror similar patterns seen in traditional financial markets during the same period.

Lower trading volumes during the decline reflect investor caution and further intensify price movements. When fewer buyers participate in the market, large sell orders have a greater impact on prices. The reduced liquidity makes the market more susceptible to sharp moves from whale transactions.

Technical Support Levels

The total crypto market cap now tests critical support at $3.67 trillion. A break below this level could open the door to further declines toward $3.58 trillion. Market analysts are watching these levels closely to determine if the selling pressure will continue.

For Bitcoin, holding above $108,000 becomes crucial for preventing further losses. A sustained break below this level could send the cryptocurrency toward the next support zone at $105,585. Recovery above $108,000 would be needed to invalidate the current bearish momentum.

The market downturn reflects the close connection between global financial conditions and digital asset prices. Bearish macroeconomic signals continue to weigh on sentiment across cryptocurrency markets. Lower trading volumes and increased volatility from options expiry and whale activity created perfect conditions for the September selloff.
