Quick Take
  • Billion-dollar liquidation events are no longer rare in crypto markets.
  • While these crashes often appear suddenly, on-chain data, leverage positioning, and technical signals usually reveal stress long before forced selling begins.
  • This article examines whether reconstructing major historical events can help anticipate liquidation cascades.

What Happened

At this stage of the cycle, rising leverage or open interest, for that matter, not only increases trader risk. It also raises balance-sheet and liquidity pressure on exchanges, which must ensure they can process liquidations, withdrawals, and margin calls smoothly during sudden volatility.

Market Context

Billion-dollar liquidation events are no longer rare in crypto markets. While these crashes often appear suddenly, on-chain data, leverage positioning, and technical signals usually reveal stress long before forced selling begins. This article examines whether reconstructing major historical events can help anticipate liquidation cascades.

Keep reading on for early signals and how to read them together. Throughout this piece, we analyze two major events: October 2025 (long liquidation cascade) and April 2025 (short squeeze), and trace the signals that appeared before both. The focus remains primarily on Bitcoin-specific metrics, as it still accounts for nearly 60% (59.21% at press time) of total market dominance.

On October 10, 2025, more than $19 billion in leveraged positions were taken out, making it the largest liquidation event in crypto history. Although US–China tariff headlines are often cited as the trigger, market data show that structural weakness was around for weeks. The majority of these liquidations were long-biased, almost $17 billion.

Price Extension and Leverage Expansion (Sep 27 → Oct 5)

During the same period, open interest rose from roughly $38 billion to more than $47 billion. Leverage was expanding fast, indicating growing dependence on derivatives.

Gracy Chen, the CEO of Bitget, said modern market structure makes leverage far more synchronized than in earlier cycles.

When asked how platforms prepare for such periods, Chen, said risk management starts long before volatility erupts:

“Holding a strong BTC reserve is a risk management decision before it’s a market view… prioritize balance-sheet resilience… avoid being forced into reactive moves when volatility spikes…,” she said

Short-Term Holders Flip From Capitulation to Optimism (September 27 → Oct 6)

Short-term holder NUPL (Net Unrealized Profit/Loss), measuring paper profits or losses. provided one of the clearest warning signals. On September 27, STH-NUPL stood near -0.17, reflecting recent capitulation. By October 6, it had surged to around +0.09.

Why It Matters

This pattern suggests a gradual transfer from early participants to late entrants, often seen near local tops.

Such rapid transitions are dangerous. After emerging from losses, traders often become highly sensitive to pullbacks and eager to protect small gains, increasing the risk of sudden selling.

October 10, 2025 — The Largest Long Liquidation Cascade Came With Signs

Between September 27 and October 5, Bitcoin rallied from around $109,000 to above $122,000, eventually testing the $126,000 area. This rapid move strengthened bullish sentiment and encouraged aggressive long positioning.

“Positions are built and unwound faster, across more venues… leverage behaves more synchronously… When stress hits, the unwind is sharper, more correlated, and less forgiving,” she added.

At the same time, exchange inflows fell from around 68,000 BTC to near 26,000 BTC. Holders were not selling into strength. Instead, supply stayed off exchanges while leveraged exposure increased.

This combination reflected a late-stage rally structure.

Profit-Taking Beneath the Surface (Late Sep → Early Oct)

On-chain profit data showed that distribution had already begun.

From late September into early October, Spent Output Profit Ratio (SOPR), which tracks whether coins are sold at profit or loss, went up from around 1.00 to roughly 1.04, with repeated spikes. This indicated that more coins were being sold at a profit.

Importantly, this happened while exchange inflows remained low. Early buyers (possibly already exchange-held supply) were quietly locking in gains without triggering visible selling pressure. And BTC was already at an all-time high during that time.

In less than ten days, recent buyers moved from heavy losses to clear profits.
