Bitcoin Crashes Toward $80K as ‘Great Crypto Crash of 2025’ Turns Q4 Into Worst Slump Since 2022
Bitcoin fell as much as 6.4% to $81,600 on November 21, 2025, before rebounding near $84,000, marking its worst month since the 2022 crypto collapse. The selloff erased over $1 trillion from crypto markets since October, with Bitcoin down more than 20% in November and negative for the year. Ethereum dropped below $2,700, hitting a four-month low. The slump follows ETF outflows and a global retreat from risk assets.
