Bitcoin crashed below 81,000 dollars in early October 2026, wiping out over a billion dollars in leveraged bets in a single day.
02
The slide started October 5 as US Bitcoin ETFs posted their largest single-day outflow since June: about 487 million dollars.
03
By October 8, Bitcoin had fallen from near 87,000 dollars to an intraday low around 80,400 dollars.
04
Coinglass data showed roughly 1.16 billion dollars in crypto liquidations over 24 hours, more than 90 percent of it long positions.
05
A bond market selloff and a rally in oil prices added pressure, pushing the 10-year Treasury yield above 5.3 percent.
06
Liquidations happen when leveraged traders run out of collateral to cover losses and exchanges close their positions automatically.
07
Forced selling from long liquidations pushes the price down further, which triggers more liquidations in a self-feeding cascade.
08
This was far smaller than October 2025's roughly 19 billion dollar wipeout, but still one of 2026's largest single-day liquidation events.
