Bitcoin跌破$67K, BTC-USD -23% W/Losses Since Trump Win; ETH, SOL Fell 33% and 30%

Bitcoin fell below $67,000 on February 5, 2026, to $66,753, per CoinGecko, erasing all gains since shortly after Donald Trump's election win in December 2024. The decline continued broader risk-off sentiment: Ethereum dropped 33% to $1,936 and Solana 30% to $84 over the past week. On the same day, the Nasdaq fell 1.6% and the S&P 500 1.2%, according to Yahoo Finance. Analyst Carlos Guzman of GSR said weakness in tech and AI-related indices, including a 3% drop in the S&P 500 software and services index, is weighing on crypto. The release of new legal tools by Anthropic for its Cowork product has heightened concerns about AI disruption, contributing to the broader sell-off in risk assets.
