Efluxos de ETFs de Bitcoin: ¿Un señal bajista o una corrección táctica?

The recent $934.8 million three-day outflow from Bitcoin ETFs in early January 2026 has sparked debate about the sustainability of Bitcoin's bull case. With Q4 2025 marking the largest ETF outflows since the product's launch-$5.5 billion in total-investors are grappling with whether this reflects a broader bearish trend or a tactical response to macroeconomic headwinds. To assess this, we must dissect the interplay between ETF flows, on-chain fundamentals, and historical market behavior.

ETF Outflows and Institutional De-Risking

The outflows in Q4 2025 were driven largely by institutional investors, with BlackRock's iShares Bitcoin Trust (IBIT) alone recording a $435 million weekly outflow. This aligns with a broader risk-off environment, as macroeconomic uncertainties-such as hawkish Federal Reserve policy and inflation concerns- prompted investors to rebalance portfolios. Notably, the $1.1 billion in outflows from January 6–8, 2026, were not panic-driven retail exoduses but calculated adjustments by institutions, as seen in the orderly unwinding of positions in major ETFs like Fidelity's FBTC.

This behavior mirrors historical patterns: in November 2025, Bitcoin ETFs saw $3.6 billion in outflows amid a 4.4% decline in the S&P 500, underscoring the growing correlation between Bitcoin and traditional assets. The 0.5–0.88 correlation range observed in 2025-up from near zero in 2018–2020- reflects Bitcoin's integration into institutional portfolios and its sensitivity to macroeconomic cycles.

On-Chain Fundamentals: Weakness or Resilience?

Bitcoin's on-chain activity tells a mixed story. Active addresses hit a one-year low of 660,000 (7-day moving average) in Q4 2025, signaling reduced peer-to-peer usage and a shift toward store-of-value dynamics. The Network Value to Transactions (NVT) ratio, a metric that gauges market value relative to transaction throughput, also raised concerns about long-term blockspace demand. Meanwhile, miner balances declined as daily revenue dropped from $50 million to $40 million, with hash rate falling 4% in December 2025- the sharpest drop since April 2024.

However, these metrics may not all be bearish. A declining hash rate is historically a contrarian bullish signal, as it suggests miner capitulation and reduced selling pressure. Additionally, while medium-term holders (1–5 years) are selling, long-term holders (>5 years) remain stable, indicating that the core demand for Bitcoin as a store of value persists.

Bearish Signal or Tactical Correction?

The key question is whether these outflows represent a structural breakdown or a cyclical correction. On one hand, the synchronized decline in ETF flows, on-chain activity, and miner revenue suggests a coordinated de-risking. The collapse of the basis trade post-ETF launch in 2024 further exacerbated selling pressure, as traders unwound positions. On the other hand, Bitcoin's price has shown resilience, stabilizing above $85,000 despite outflows and even edging toward $90,000 with renewed ETF inflows in late 2025.

Historically, Bitcoin ETFs have drawn $54.75 billion in net inflows since their 2024 launch, reducing daily volatility from 4.2% to 1.8%. This suggests that while outflows are painful in the short term, the structural tailwinds of institutional adoption and reduced volatility remain intact.

Investment Implications

For investors, the current environment demands a nuanced approach. Short-term risk-off behavior is likely to persist as macroeconomic data remains mixed, but the bearish case hinges on whether on-chain weakness-such as declining active addresses and miner balances-translates into sustained selling pressure. Conversely, the bull case rests on the idea that these outflows are a tactical correction within a longer-term uptrend, with miner capitulation and ETF inflow history acting as potential catalysts for a rebound.

Strategically, investors might consider hedging against macroeconomic risks while maintaining exposure to Bitcoin through diversified ETFs or on-chain metrics that signal capitulation. The key will be monitoring whether the $85,000 support level holds and whether institutional inflows resume as macroeconomic clarity emerges.
