Bitcoin's price fell from over $126,000 to $122,000 on October 8, 2025, as the US dollar surged and market volatility increased. Analysts point to market overheating and heightened institutional activity as key factors in the decline. Major altcoins, including XRP, DOGE, and ADA, also saw declines of 4%-5%. Experts from Deribit and K33 suggest a potential pullback to the $118,000–$120,000 range, highlighting ETF and derivatives inflows as indicators of an overheated market.
