Bitcoin Has Entered A Bear Market, And This Data Backs It Up

The ongoing Bitcoin price play out leading into a bear market is now one of the most pressing questions in the crypto industry. Right now, Bitcoin is trading between $87,700 and $88,000, which is a 30% drop from the all-time high it reached in October 2025. 

Price action alone often leaves room for debate, but on-chain data is beginning to offer clearer guidance. Notably, analysis from CryptoQuant shows that Bitcoin’s internal market structure is shifting in a way that aligns more closely with early-stage bear market conditions.

The important bear market signal is from Bitcoin’s Combined Market Index, or BCMI, which is a composite indicator that blends price behavior with on-chain momentum. According to Woo Minkyu, a verified analyst on the CryptoQuant platform, Bitcoin’s BCMI returned to the 0.5 level in October. This was initially interpreted as a cooling phase rather than a definitive cycle top. At the time, the assumption was that Bitcoin was consolidating after an extended rally.

However, that view has weakened with the deterioration of market conditions. Particularly, Bitcoin’s price action has declined materially since late October, and the BCMI has fallen in tandem with the price. This joint decline suggests the market has reset not only through time but also through valuation and participation. 

As shown on the chart below, the BCMI has now slipped below its equilibrium zone, and this is a development that is known to coincide with transitions into bearish phases, where rallies tend to be capped, and downside risks increase.

A closer look at prior Bitcoin cycles adds more context to the current setup. In both 2019 and 2023, meaningful cycle bottoms formed only after BCMI compressed into the 0.25 to 0.35 range. Those levels reflected deep sentiment compression, washed-out positioning, and a structural reset of the market.

At current readings, Bitcoin’s Combined Market Index is less than 0.4. This reading is below equilibrium but still well above a bottom zone. This opens the possibility that the market is transitioning into a bear phase, not just experiencing a pullback.

According to the analyst, a more durable bottom may only form if history repeats itself and the BCMI revisits 2019-2023 levels.

Market sentiment is also supporting the idea that Bitcoin is moving deeper into a bearish phase. Optimism has been really scarce in recent weeks, with traders showing little confidence that the price has found a sustainable floor. CoinMarketCap’s Crypto Fear and Greed Index is currently posting a reading of 28, which places sentiment firmly in the Fear zone.

This poor sentiment backdrop has been affirmed by industry commentary. For instance, Changpeng Zhao recently noted that many investors only wish they had bought Bitcoin early when prices were already at all-time highs. In practice, those early accumulations happened during periods like the present one, when fear, uncertainty, and doubt dominate market psychology.
