Bitcoin historically experiences a decline in September, with an average drop of 6% over the past 12 years, according to CoinDesk data. This trend is compounded by a decrease in MicroStrategy's Bitcoin premium, indicating market concerns over corporate financial strategies involving cryptocurrency. Analysts suggest that while a potential Federal Reserve rate cut could alleviate some pressure, ETF fund outflows or stock market sell-offs might push Bitcoin's price towards the $100,000 support level. Since 2013, Bitcoin has closed lower in September eight times, with significant declines of 13% in 2019 and 19% in 2014. This pattern has led traders to view September as a challenging month for Bitcoin, often resulting in a fixed trading cycle that anticipates seasonal weakness.
