Bitcoin is experiencing its worst October performance in a decade, with prices down 5% this month to approximately $107,000, significantly below the historical average gain of 19.8%. The decline is attributed to macroeconomic risks, including U.S.-China tariffs and weak liquidity, which have led to $1.2 billion in liquidations. Other major cryptocurrencies such as Ethereum, Solana, and BNB have also seen declines of 4%-7% weekly, while smaller tokens like Dogecoin and ADA have dropped over 20%.
