Bitcoin's $20B Liquidation Crash: What Traders Must Learn
One year after crypto's worst forced-selling event ever, the dangerous mechanics that caused it haven't changed.
A year ago this weekend, Bitcoin was riding high at a record $126,080. Then came a single political headline — President Trump announcing 100% tariffs on Chinese imports — and within days, the crypto market was in freefall. Around $20 billion in leveraged positions got wiped out over one brutal weekend in October 2025. Today, Bitcoin still sits roughly a third below that peak, and the lesson hasn't fully sunk in for a lot of traders.
Here's the part worth understanding if you use leverage: when a leveraged position gets too underwater, exchanges automatically close it and sell your assets into the market. That forced selling drags prices lower, which triggers *more* liquidations, which drags prices even lower. That chain reaction is called a liquidation cascade, and thin weekend trading makes it nastier because there aren't enough buyers to absorb the pressure. At 25x leverage, a mere 4% price move against you can zero out your margin entirely.

The kicker is that the tariff news wasn't the whole story. The real damage came from how much leverage had quietly piled up beforehand, just waiting for something — anything — to set it off. Bitcoin dropped nearly 15% and Ether fell more than 20% in that stretch. Spot Bitcoin and Ether ETFs saw combined outflows exceeding $755 million when US markets opened Monday.
There's also a behavioral trap baked into this story. Bitcoin has historically closed October in the green 10 out of the last 13 years, earning the month its cheerful "Uptober" nickname. That track record made traders complacent heading into last October — when Bitcoin hit an all-time high early in the month, then crashed, and still finished down 3.7%. Seasonal patterns describe history; they don't protect your portfolio.
This October, the macro backdrop arguably matters more than any calendar superstition. The Federal Reserve meets on October 27–28, and rate hikes remain a real possibility. Analysts at Bitfinex have suggested Bitcoin's biggest constraint right now isn't crypto sentiment but the return available on boring, low-risk assets. If safe yields stay attractive, speculative bets look less appealing by comparison. Continue reading at Forexlive.
