Which Altcoins Could Crash if Bitcoin Closes Below $100,000?

Bitcoin briefly slipped below the $100,000 mark a few hours back, shaking market confidence and sparking fresh volatility. As traders assess the next move, attention is turning to the altcoins that could crash if Bitcoin falls further, given their tight price link with BTC. With Bitcoin’s dominance climbing again, several highly correlated tokens are already flashing signs of weakness. These three coins often move in lockstep with Bitcoin — and if BTC slides deeper, their declines could quickly intensify.

Bitcoin Cash (BCH)

Bitcoin Cash could be one of the altcoins to crash if Bitcoin falls, given its strong price link with BTC. Its 7-day Pearson correlation coefficient is 0.94, showing that BCH moves almost exactly in step with Bitcoin. The Pearson coefficient measures how closely two assets move together, with +1 meaning they move the same way and -1 meaning the opposite.

Even over the past year, BCH has maintained a high 0.80 correlation, making it one of the most consistently linked assets to Bitcoin’s movements.

That connection is already visible in recent price action. Over the past month, Bitcoin Cash has dropped 18.9%, while Bitcoin has fallen 18.1% — showing both are still moving in tandem. As Bitcoin dominance climbs above 60%, this tight correlation makes BCH especially vulnerable to any deeper Bitcoin decline. Large holders — the 100,000 to 1 million BCH cohort, often considered whales — have been reducing positions since November 1, cutting their stash from 4.39 million to 4.34 million BCH, or roughly 50,000 coins (about $25 million).

BCH Whales

On the charts, BCH trades near $484. If Bitcoin weakens further, $439 is the next key support, below which a larger breakdown could begin. However, if BTC rebounds, BCH is likely to follow quickly.

BNB (BNB)

BNB is another major altcoin to crash if Bitcoin falls, given its consistently strong correlation with BTC. The 7-day correlation between the two stands at 0.97, showing they move almost together.

BNB-BTC 7-day Correlation

Over the longer term, the one-year coefficient sits at 0.67, which still signals a strong positive link. That correlation is already visible in recent price data. BNB and Bitcoin have both corrected by over 4% in the past 24 hours.

 BNB-BTC Yearly Correlation

The coin has followed BTC closely through this correction phase. However, despite the weakness, BNB remains one of the strongest performers of this cycle, still up 23.5% over the past three months.

If Bitcoin manages to recover further, BNB could be one of the first coins to benefit. For that to happen, the price must hold above $946 to confirm a rebound setup. Between October 10 and November 4, the price made a higher low while the Relative Strength Index (RSI) made a lower low — a hidden bullish divergence that hints at an ongoing uptrend beneath the correction. This pattern lends weight to the rebound setup, but only if BTC keeps strong.
