Bitcoin (BTC) is struggling to maintain support at $80,000 as the market enters a critical week defined by US Federal Reserve policy decisions and major corporate earnings reports. The asset began the final week of October trading near this psychological threshold, with recent price action showing significant volatility; specifically, nearly $150 million in long positions were liquidated over two hours on Saturday when BTC dipped to $79,145. Despite historical seasonal trends that often favor October gains—dubbed 'Uptober' with an average 26.1% upside since 2010—current conditions have bucked this pattern, leaving Bitcoin on track for a 4% monthly decline if prices remain near current levels.

The macroeconomic backdrop centers on the upcoming Federal Open Market Committee (FOMC) meeting on Wednesday, where markets anticipate a decision on the federal funds rate. Current data indicates over 90% odds that rates will remain unchanged within the 3.75-4% range, though consensus favors a potential 0.25% hike at the subsequent December meeting. Economist Robin Brooks noted that low market interest in this specific meeting provides a temporary reprieve for Fed Chair Kevin Warsh, arguing that tightening financial conditions elsewhere make an immediate hike unlikely despite rising oil prices and geopolitical tensions.

Equity markets are also under pressure ahead of key earnings releases from tech giants Microsoft, Alphabet, Amazon, and Intel later in the week. Recent performance has been weak, with the Nasdaq Composite closing at its lowest daily level since August 3 and South Korea’s KOSPI index falling 1.5%. Analysts suggest investor sentiment is shifting away from rewarding capital expenditure growth toward prioritizing return on capital, particularly in the AI sector. Additionally, new Personal Consumption Expenditures (PCE) data and US Q3 GDP figures are scheduled for release, further influencing market expectations.
