One year after crypto's $19 billion crash, bitcoin's order books are 75% deeper, but the leverage never left

A year ago today, crypto had its worst day on record. Bitcoin dropped from about $122,000 to $105,000, most of it within minutes, days after hitting a record above $126,000. More than $19 billion in leveraged bets were wiped out in a single day.

The market has rebuilt some of its plumbing. Bitcoin's order-book depth within 1% of the price, a measure of how much can be traded without moving it, is about $11.7 million, roughly 75% above crash day, according to CoinDesk Research. Ether's depth within 0.5% has more than doubled to about $4.2 million. "The majors' deepening is real capital, not a price effect," CoinDesk researcher Saksham Diwan said.

The rest of the market is thinner. Depth for other altcoins within 5% of price is down about a third since early 2025, to about $2 million. And weekly spot trading on centralized exchanges averaged about $279 billion in the four weeks to September 27, nearly two-thirds below the $801 billion traded in the crash week.

The risk that caused the crash is still there. "The levered products have not gone away," Mark Connors of Risk Dimensions told CoinDesk. "The market did bend; it didn't break."

What to watch: September inflation data next week and the Fed meeting on October 27 and 28, both of which can move leveraged positions fast.
