Why did Bitcoin plummet 10%: it lost the support of $84,600, the on-chain structure collapsed first, and liquidation is just the result.

January 30 News, Bitcoin has fallen over 10% from its late January high, briefly dropping below $81,000 before rebounding above $82,300. In the past 24 hours, the forced liquidation in the crypto market exceeded $1.7 billion, with nearly $800 million in Bitcoin longs liquidated. At first glance, the crash appears to be triggered by leverage, but on-chain data reveals that the true decline had already begun before the price broke down.

The first warning sign appeared on the daily chart. Bitcoin recorded its largest bearish candle since December of last year, with increased volume but no effective support. Subsequently, the key support level of $84,600 was broken, and the price quickly slid into the $81,000 range. This breakdown pushed Bitcoin into a critical zone where UTXO realized price distribution is densely concentrated.

On-chain data shows that the two largest cost clusters are at $84,569 and $83,307, accounting for over 5.7% combined. When the price falls into this range, a large amount of holdings start to realize losses, sharply increasing selling pressure. Glassnode data indicates that long-term holders experienced a significant reduction in holdings on January 29, with a 30-day net change of -144,684 BTC, hitting a new low for the period. In other words, seasoned investors quietly sold off at their core cost basis, undermining the most critical structural support.

Why did previous indicators seem healthy? The reason lies in the mixed interpretation of data from different holding periods. Mid-term funds and large addresses continued to accumulate, while long-term holders sold in high-density zones. When the ‘belief-driven’ positions start to exit, even if the surface balance appears strong, the market is already hiding risks.

After support collapsed, leverage became an amplifier. CoinGlass shows that nearly $800 million in long positions were liquidated within 24 hours. Derivatives were not the trigger but a chain reaction resulting from the breakdown of spot market structure.

From a technical perspective, Bitcoin has broken below the head and shoulders neckline, indicating approximately 12% further downside potential, with a target area possibly around $75,000. The short-term key support is at $81,000; first, the market needs to recover $83,300. The real critical level separating bulls and bears remains at $84,600. Until the price re-establishes above this cost zone, any rebound will remain fragile.
