Bitcoin's Critical $70,000 Support: A Gateway to a Year-Long Bear Market or a Buying Opportunity?

The Bitcoin price action at the $70,000 support level in late 2025 has become a focal point for investors and analysts, with on-chain metrics and historical market cycles offering conflicting signals. Is this level a fragile floor that could trigger a prolonged bear market if breached, or a strategic accumulation zone for long-term holders? To answer this, we must dissect the interplay of on-chain risk indicators and historical precedents.

On-Chain Risk Indicators: A Mixed Bag

Bitcoin's MVRV Z-score currently hovers near 2, a level that historically suggests the market is still below euphoric overvaluation but not yet in undervalued territory according to analysis. This metric, which compares Bitcoin's price to its on-chain realized value, indicates that long-term holders (LTHs) are still distributing coins into strength. Active LTH supply has declined by ~507K BTC as prices hit new highs, signaling ongoing sell-side pressure. Meanwhile, the Short-Term Holder (STH) Net Unrealized Profit/Loss (NUPL) metric has dipped to –0.05, reflecting moderate stress but not full capitulation. This aligns with mid-bull corrections rather than bear market bottoms.

The Network Value to Transactions (NVT) score, however, tells a different story. While not explicitly quantified in recent data, structural trends suggest Bitcoin's valuation is evolving toward a store-of-value model. Miner revenues have stabilized post-halving, but low fees persist, creating fragility in long-term incentives according to analysis. The continued outflow of ~–104K BTC monthly by LTHs underscores fragile demand amid ongoing distribution according to data.

Historical Context: Lessons from 2018–2020 and 2021

During the 2018–2020 bear market, Bitcoin's MVRV Z-score plummeted to –0.49 in December 2018 and –2.1 in March 2020, marking extreme undervaluation. These levels coincided with critical support zones that eventually catalyzed rebounds. Similarly, in 2021, the MVRV ratio hit 3.618 before the $69,000 peak, a threshold that could reemerge as a target if current trends mirror historical patterns.

The NVT ratio during these bear phases also highlighted overvaluation when market cap surged without proportional transaction volume according to analysis. For instance, in 2017, the NVT ratio flagged overvaluation as Bitcoin's price outpaced network activity, foreshadowing the 2018 crash. Today, the NVT score remains ambiguous, but the lack of robust transaction volume at $70,000 suggests weak on-chain support.

The $70,000 Zone: A Weak but Pivotal Support

Bitcoin's current $70,000–$80,000 range is historically underdeveloped, with the asset spending only 28 trading days in this band over the past five years. This sparse consolidation is corroborated by the UTXO Realized Price Distribution (URPD), which shows minimal supply concentration in this range according to analysis. If Bitcoin fails to hold above this level, it may need to retest it repeatedly to build stronger structural support according to data.

The STH realized price currently sits at $113,000 according to analysis, meaning short-term holders are in profit at $70,000. This could foster investor confidence if the price holds, potentially triggering the next bull phase. However, the MVRV ratio above 0.66 suggests a potential accumulation phase according to data, with resistance projected at $160,000–$200,000 if the STH cost basis is maintained according to analysis.

A Bear Market Catalyst or a Buying Opportunity?

The $70,000 level's vulnerability lies in its weak historical footprint. If Bitcoin breaks below this threshold, it could face deeper retracement toward the Active Investors' Realized Price (~$88K) according to data. This would mirror the 2018–2020 bear market, where breakdowns in key support levels led to prolonged drawdowns. Conversely, if the price consolidates above $70,000, the STH MVRV ratio and LTH distribution patterns suggest a path to $163,000–$165,000 according to analysis, aligning with historical bull cycle peaks.

Conclusion: Navigating the Crossroads

Bitcoin's $70,000 support level is a crossroads. On-chain metrics like the MVRV Z-score and NVT ratio suggest a fragile equilibrium, with LTH distribution and weak historical consolidation posing risks. However, historical parallels to 2018–2020 and 2021 indicate that this level could serve as a buying opportunity if accumulation takes hold. Investors must monitor the STH realized price and MVRV thresholds closely, as a failure to hold above $70,000 could signal the start of a year-long bear market, while a successful defense might herald the next leg of the bull cycle.
