La transición de Bitcoin al mercado de bajistas en 2025: ciclos impulsados por la demanda, señales de cadena, y posicionamiento estratégico

The cryptocurrency market in 2025 has been a rollercoaster of institutional optimism and macroeconomic turbulence, with Bitcoin at the center of a maturing demand-driven cycle. As the year draws to a close, a confluence of weakening ETF flows, on-chain bearish signals, and geopolitical headwinds-particularly under the Trump administration's trade policies-has painted a complex picture of a market transitioning into a bear phase. This analysis unpacks the evidence, from institutional behavior to technical indicators, and offers strategic guidance for investors navigating this pivotal moment.

Weakening ETF Flows: A Harbinger of Institutional Caution

The third quarter of 2025 saw a record $12.5 billion in net inflows into global Bitcoin ETFs, driven by institutional adoption and a 57% contribution from investment advisors. However, this momentum reversed sharply in Q4, with November alone witnessing $3.79 billion in outflows. This shift reflects a combination of profit-taking, macroeconomic uncertainty (as the Fed signaled prolonged higher rates), and a rotation of capital into higher-beta altcoins like Solana as reported by analysts.

While BlackRock's IBIT and Fidelity's FBTC continued to attract inflows in early December-such as a $457 million single-day surge according to market data-the broader trend reveals instability. By Q4, U.S. spot Bitcoin ETFs became net sellers, offloading 24,000 BTC. This divergence between short-term inflows and long-term outflows underscores a cooling of institutional demand, a classic precursor to bear markets.

On-Chain Indicators: A Bear Market in the Making

On-chain metrics have long served as canaries in the coal mine for Bitcoin's cycles, and 2025's data is no exception. The MVRV (Market Value to Realized Value) ratio, a key sentiment gauge, crossed its 30-day moving average below the 365-day line in August-a "death cross" historically linked to sharp sell-offs. While the current MVRV ratio of 2.1 remains in a "neutral to bullish" zone, it has diverged from the 3.5–4.0 overvaluation range seen in previous tops as noted in market analysis.

The NVT (Network Value to Transactions) ratio, meanwhile, hit a golden cross at 1.51, suggesting Bitcoin's valuation is supported by real transactional activity rather than speculative fervor. However, this metric must be contextualized: 74% of circulating BTC is illiquid, and the SOPR (Spent Output Profit Ratio) of ~1.03 indicates minimal profit-taking, signaling a market in consolidation according to on-chain data.

Whale activity further complicates the narrative. A 40,000 BTC cold storage transfer in July 2025 and the fact that 64% of Bitcoin's supply is controlled by long-term holders suggest strategic accumulation rather than panic selling as observed by analysts. Yet, the MVRV Z-score of 2.31 in Q4-a measure of overheating-aligns with historical bear market triggers according to Tiger Research.

Macro Events: Trump's Tariffs and Trade Tensions

The Trump administration's 10% global tariff policy in 2025 introduced unprecedented uncertainty, triggering a nearly 10% drop in Bitcoin's price within days of the announcement. While trade tensions historically boost Bitcoin's safe-haven appeal according to market reports, the 2025 environment has been unique: stablecoins, not Bitcoin, have dominated corporate transactions, with 30% of on-chain volume tied to USD-pegged assets as detailed in a 2025 report.

The U.S. GENIUS Act's mandate for stablecoin audits has reinforced trust in these instruments, enabling businesses to bypass traditional banking friction. This shift highlights a critical divergence: while Bitcoin remains a speculative asset, stablecoins are becoming the preferred medium for real-world transactions during geopolitical instability.

Key Support Levels and Strategic Positioning

Bitcoin's price in Q4 2025 fell 30% below $90,000, breaching the 50-week EMA-a critical technical level historically associated with bull-to-bear transitions. Analysts like Arthur Hayes argue that $80,000 could act as a short-term floor, with a potential rebound to $120,000 if liquidity stabilizes as noted in market analysis. However, a breakdown below $80,000 could trigger cascading stop-loss orders toward $74,000–$76,000 according to trading insights.

For strategic positioning, investors must monitor volume dynamics and on-chain data. If $80,000 holds, it could provide a foundation for a 2026 rally. Conversely, a failure to stabilize here may extend the bear phase into late 2026, with $56,000 as a potential target according to market forecasts. Derivatives markets also signal caution, with reduced appetite for leveraged longs and ETF outflows exacerbating downward pressure as reported by analysts.

Conclusion: Navigating the Transition

Bitcoin's 2025 bear market transition is a textbook example of a demand-driven cycle maturing. Weakening ETF flows, on-chain bearish signals, and macroeconomic headwinds collectively point to a market correcting after years of institutional adoption. While the long-term fundamentals-such as post-halving supply constraints and regulatory clarity-remain intact according to institutional research, short-term volatility is inevitable.

Investors should adopt a disciplined approach: use key support levels as buying opportunities if fundamentals hold, while maintaining tight risk controls. The coming months will test whether Bitcoin's institutional demand can withstand the storm-or if the market will enter a prolonged bear phase.
