When October 10, 2025 began, few crypto traders expected it would become known as “Crypto Black Friday.” The digital currency markets experienced their most devastating crash in history, with over $9.89 billion in positions liquidated within just 14 hours.
The chaos started when President Trump announced a 100% tariff on Chinese imports. This news hit crypto markets like a wrecking ball, triggering massive panic selling.
What made this crash truly terrifying was its speed. In just 40 minutes, $19.20 billion worth of leveraged positions vanished into thin air.
Bitcoin, usually the steady giant of crypto, fell 6.84% from $121,576 to $113,263. But altcoins got absolutely hammered. UNI crashed 26.92% with a brutal 70.10% intraday drawdown. AAVE and AVAX weren’t much luckier, both suffering maximum drawdowns near 70%.
Even the beloved meme coin DOGE couldn’t escape, dropping 64.72%.
The market mechanics told a scary story. Order book depth evaporated by 98%, shrinking from $103.64 million to just $0.17 million. Imagine trying to sell your crypto when there were barely any buyers left.
Bid-ask spreads widened 1,300 times their normal size, making trading feel like highway robbery.
What really amplified the damage was leverage. Around 87% of liquidated positions were long trades, meaning traders had bet big that prices would go up.
When prices crashed instead, their borrowed money disappeared faster than ice cream on a hot day. Over $19 billion in leveraged positions got wiped out within 24 hours.
The crash exposed serious flaws in the crypto system. Oracle failures caused USDe to trade 35% below its $1 target on Binance.
Liquidity providers ran for the hills when things got rough, leaving regular traders stranded. Major exchanges showed thin order books with bids positioned 4-10% away from mid-price, creating a devastating no-bid environment. Despite the massive liquidations and market chaos, regulatory authorities remained notably silent with no official statements or actions issued following the unprecedented crash.
Dubbed the “Great De-Leveraging,” this event became a harsh reminder of crypto’s wild nature. While excessive leverage got purged from the system, the crash highlighted risks that go far beyond normal market dips. This catastrophic event reinforced why defensive strategies that focus on fundamentals and long-term value remain superior to chasing speculative trends.
October 2025 will be remembered as the month when reality gave crypto markets a brutal wake-up call.
