Bitcoin drops to $81,400 as tech earnings and capex concerns trigger broad risk-off sell-off

Bitcoin traded around $81,400 after falling nearly 3%, pressured by a risk-off retreat across global markets following corporate earnings. The decline came after Bitcoin faced technical rejection near $84,840. Broader sentiment soured following quarterly reports and reduced capital expenditure projections from major tech firms, including Tesla reporting third-quarter capex of $4.73 billion versus the $7.96 billion expected. The pullback triggered approximately $272 million in long liquidations across crypto derivatives markets, pushing prices toward the pivotal $80,000 to $81,500 support range representing the aggregate cost basis for U.S. spot Bitcoin ETF investors.
