Bitcoin has reclaimed the $80,000 mark after a period of volatility that saw its price drop below $75,000 over the weekend. The cryptocurrency briefly reached as high as $81,000 during its recovery, which coincided with a rebound in U.S. stock markets, including the Nasdaq and S&P 500, that avoided a 'Black Monday'-style collapse. Analysts note that Bitcoin's price recovery aligns with significant support levels identified by on-chain data, including $74,000 and $70,000, where substantial investor activity has been recorded. The rebound follows a dip to five-month lows, with the cryptocurrency showing relative strength compared to traditional markets, despite global economic uncertainty.
