TLDR:Bitcoin dropped from $78,000 to below $77,000 in one hour, erasing over $100M in leveraged long positions.Weekend order books lacked institutional depth, making prices far more sensitive to forced market sell orders.Whales and hedge funds actively target liquidation clusters to trigger cascades and buy assets at lower prices.Open interest has rebuilt to $25B post-drop, signaling renewed leverage risk and potential for another sharp correction.Bitcoin experienced a sharp price decline in late April 2026, dropping from around $78,000 to below $77,000 within an hour. Over $100 million in leveraged long positions were wiped out during that period. Analysts point to forced liquidations rather than organic selling as the main driver. Weekend trading conditions made the move worse, as thin order books left prices exposed to sudden pressure from automated sell orders.Weekend Market Conditions Worsened the Liquidation CascadeLow-liquidity periods, such as weekends, create conditions where even modest capital can shift prices sharply. Institutional traders and liquidity providers step back during these windows, leaving order books thin. As a result, market orders carry more weight and move prices faster than they would on regular trading days.Once Bitcoin breached key margin thresholds, automated systems triggered forced liquidations on leveraged long positions. These sell orders then fed into an already fragile order book. The cascade that followed amplified downside momentum well beyond what spot selling alone could have produced.As noted by Cryptoquant analyst @xwinfinance, “With reduced participation from institutions and liquidity providers, order books become thin, making prices more sensitive to market orders.” This structural weakness is not unique to this event but is a recurring feature of weekend crypto trading.Algorithmic trading systems accelerated the move further. These programs react to price changes in milliseconds, adding sell pressure on top of forced liquidations. The combination of thin liquidity and automated responses created the conditions for a rapid and outsized drop.Professional Players Often Target Liquidation Zones for ProfitMarket makers, whales, and hedge funds routinely monitor order book data and derivatives metrics to identify where liquidation clusters sit. By pushing price into those zones, they can trigger forced selling and buy back at lower levels. This turns liquidation events into profitable setups for well-capitalized traders.This strategy works most effectively during low-liquidity sessions. Smaller amounts of capital are needed to move price into liquidation territory when fewer participants are active. The cost of executing such a move drops significantly on weekends or during off-peak hours.Open interest data across exchanges shows that leverage has rebuilt to around $25 billion alongside the recent price recovery. That figure points to renewed risk appetite and a return of leveraged positioning. The market is once again vulnerable to similar liquidation-driven moves if prices shift unexpectedly.The cycle of leverage rebuilding after liquidation events is a known pattern in crypto markets. Traders re-enter leveraged positions after a flush, gradually pushing open interest back up. Until market structure deepens and liquidity improves, these sharp, position-driven drops are likely to remain a recurring feature of Bitcoin trading.The post Bitcoin $78K Crash Explained: How Leverage Liquidations Triggered a Cascading Sell-Off appeared first on Blockonomi.
