Just looked at Coinglass's liquidation data and found that Bitcoin at this price level is indeed quite interesting. If BTC surges to 73k, mainstream exchanges would need to liquidate shorts worth 834 million, and conversely, if it drops below 69k, long liquidations would reach 940 million.

In simple terms, these two price points are both risk concentration zones, and once touched, they can easily trigger a chain reaction. The taller the "columns" on the liquidation chart, the more intense the liquidity shock at that price point. It's not about the exact number of contracts to be liquidated, but about showing the relative strength—where the liquidation pressure is the greatest.

Currently, BTC is hovering around 77k, feeling still some distance from these two key levels, but traders are probably watching these data closely. Especially those with high leverage positions, they should pay attention to these liquidation concentration zones.
