Bitcoin weighs quantum risk as $55K support eyed

What to Know:

• Evidence doesn’t support a one-year Bitcoin plunge to $30,000 from quantum.
• Quantum-resistant migration is multi-year; institutions don’t foresee a $30,000 shock.

Claims that Bitcoin could fall to $30,000 next year solely because of quantum-computing risk are not supported by current evidence from institutions and developers. The threat exists, but timelines and implementation realities do not point to an imminent, one-year price shock tied only to a missing “quantum-proof” upgrade.

Migration to quantum‑resistant signature schemes is generally framed as a multi‑year effort, often five to ten years, signaling a serious but not immediate risk, as reported by Coin-Views. This suggests pricing a near-term collapse purely on quantum fears overstates what experts currently outline.

Academic modeling of upgrade logistics further indicates complexity rather than immediacy. One study estimated at least ~76 days of downtime, or roughly ~305 days via a gradual approach without a shutdown, as reported by Fortune.

Institutional risk frameworks are evolving, but even high-profile portfolio shifts have not connected a specific $30,000 downside next year directly to the absence of quantum‑resistant changes. The discussion remains a long‑tail security consideration, not a dated, one‑year price call.

Why this narrative matters now: price pressure, sentiment, support

Bitcoin’s drawdown and shifting market structure make risk narratives more salient. The asset is down about 45% from its all‑time high near $126,000 set in September 2025, as reported by CaptainAltcoin.

Market participants are watching realized price bands and potential support zones as volatility rises. One widely tracked view highlights a possible test near $55,000 amid pressure on realized levels, as reported by CryptoRank.

The quantum‑risk angle has sharpened in headlines, adding to sentiment pressure even without new breakthroughs. “Bitcoin may tumble toward $30,000 next year unless it shows real progress toward quantum‑proof upgrades,” as reported by CryptoSlate.

At the time of writing, Bitcoin was recently quoted near $66,439, roughly 2% lower over 24 hours on February 18, 2026, based on data from Yahoo Finance. That context underscores how sentiment can swing quickly around technical and macro narratives.

Key expert positions: Jefferies, Grayscale, and developer timelines

An investment bank’s strategist, Christopher Wood, removed Bitcoin from a model long‑term portfolio due to concern that quantum advances could undermine cryptographic security, reallocating toward gold and miners, as reported by Business Insider. The action reflects growing institutional emphasis on long‑duration security assumptions rather than a dated price forecast.

As reported by Decrypt, the asset manager’s 2026 Digital Asset Outlook judged quantum risks real but unlikely to affect crypto market valuations in 2026. The report also framed cryptographically relevant machines as a post‑2030 probability, implying time remains for orderly mitigation.

Developer timelines emphasize pragmatic upgrade paths, wallet migration, and governance coordination, which are non‑trivial across a decentralized network. Combined with prior academic estimates of potential downtime or gradual rollouts, the base case points to careful planning rather than an abrupt, one‑year rupture.
