Bitcoin Could Fall Below $50,000 by 2028, Capriole Founder Warns

Bitcoin’s latest bearish call didn’t come from macro data or ETF flows—it came from quantum computing. Charles Edwards, founder of crypto hedge fund Capriole, argued this week that if Bitcoin fails to harden itself against quantum attacks, the market could reprice down below $50,000 by 2028 as confidence is shaken. His comments, covered by ForkLog, frame “quantum risk” as a structural overhang that the industry must start addressing now, not later. 

What is the “quantum threat” in plain English?

Bitcoin’s security relies on two pillars: digital signatures (so only the owner can spend coins) and hashing (to secure blocks). The signatures use elliptic curve cryptography (ECDSA). A sufficiently powerful fault-tolerant quantum computer could, in theory, use Shor’s algorithm to derive a private key from a public key, allowing an attacker to steal coins from addresses where the public key is exposed (for example, many historical outputs or reused addresses). Serious Bitcoin research groups have been mapping this risk and potential migration paths for years.

That doesn’t mean “tomorrow.” Most scientists and security agencies say a machine capable of breaking widely used public-key cryptography—what Google’s team calls a “cryptanalytically relevant quantum computer (CRQC)”—does not exist yet. When Google unveiled its Willow chip in late 2024, the company emphasized it cannot break modern crypto; estimates still place a real CRQC at least a decade away, and likely longer.

But standards setters are already moving

Even if Q-Day isn’t imminent, governments and standards bodies want migrations underway well before any breakthrough. In 2024, the U.S. National Institute of Standards and Technology (NIST) finalized its first post-quantum cryptography (PQC) standards—algorithms designed to withstand quantum attacks—and urged the ecosystem to begin planning upgrades. 

Across the Atlantic, the UK’s National Cyber Security Centre (NCSC) told organizations to inventory vulnerable systems by 2028, prioritize upgrades by 2031, and complete migration by 2035—a timeline meant to beat adversaries practicing “harvest now, decrypt later” (steal encrypted data today, crack it with quantum tomorrow). 

Edwards’ point dovetails with that posture: if the world is migrating to PQC and Bitcoin doesn’t clearly signal a path, risk models could shift, and so could the bitcoin price.

How realistic is a market repricing on “quantum fear”?

Markets discount future risks long before they materialize. If investors conclude that a credible CRQC is on the horizon and Bitcoin governance isn’t coordinating a fix, some portion of capital could rotate away, lowering valuations regardless of on-chain fundamentals. That’s the behavioral argument behind Edwards’ “sub-$50,000 by 2028”scenario. ForkLog characterizes his warning as contingent on inaction—not a prediction that a quantum computer will actually break Bitcoin by that date. 

On the other hand, many researchers are confident the network can adapt. Proposed paths include migrating to quantum-safe signature schemes (for example, lattice-based algorithms standardized by NIST or hash-based signatures) and hardening wallet practices (avoid address reuse; move coins that reveal public keys). The engineering is non-trivial—changes to consensus rules and mass wallet upgrades take time—but it’s tractable with community coordination.

What would a Bitcoin “PQC migration” look like?

• Protocol work: Introduce one or more post-quantum signature types so wallets can spend coins with quantum-resistant keys. This likely requires a soft or hard fork, careful review, and long lead times.
• Wallet hygiene: Encourage users to sweep coins from any outputs where public keys are known (for example, older pay-to-pubkey outputs or repeatedly reused addresses), reducing the “exposed” surface.
• Bridged era: For years, Bitcoin would support both ECDSA and PQC paths as coins move gradually. Researchers have already outlined trade-offs around transaction size, fees, and verification costs.

The takeaway: migration is a multi-year program, which is exactly why standards bodies and national agencies want planning to start early.

The signal from outside crypto

The broader security community is converging on a “migrate in the 2030s” timetable. The NCSC targets a 2028–2035 window, while the U.S. government has PQC requirements phasing into federal systems next decade. Meanwhile, the companies actually building quantum machines—Google among them—continue to stress that current devices are far from the scale needed to break today’s encryption, reinforcing that panic is premature even as preparation is prudent.

Trading takeaways: price risk vs. timeline reality

For traders, the practical question is how and when “quantum risk” might be priced. Three heuristics help:

1. Watch the roadmap, not headlines. If Bitcoin Core, major implementations, or the broader community publish a concrete PQC migration plan (BIPs, reference code, testnets), that’s a strong de-risking signal. A vacuum of detail, by contrast, can feed discounting of future cash flows and a weaker BTC forecast—the dynamic Edwards is warning about.
2. Assess wallet exposure. Coins controlled by addresses that expose public keys are theoretically more vulnerable in a quantum future. As best practices and tools push those coins into safer formats, systemic risk declines—another de-risking step the market can track.
3. Macro still rules near-term. Even if quantum concern creeps into valuations, ETF flows, rates, and liquidity will likely dominate day-to-day price action. The quantum narrative is a slow-burn repricing risk, not a minute-to-minute catalyst.

So…could Bitcoin really drop below $50,000?

It’s possible—if the market believes the network is dragging its feet while governments, banks, and Web2 systems move to post-quantum cryptography. Edwards’ call is less about predicting a specific CRQC breakthrough by 2028 and more about warning that confidence—the bedrock of any monetary asset—could erode without a visible plan. Whether Bitcoin actually revisits sub-$50k depends on the credibility and timing of that plan as much as on the physics of qubits.

Conclusion

• Capriole’s Charles Edwards says Bitcoin could slide below $50,000 by 2028 if the industry underestimates the quantum computing threat and fails to chart a migration path. 
• Experts agree a break-Bitcoin quantum computer doesn’t exist today; Google’s team says we’re still well short of a cryptographically relevant device. 
• But standards bodies and cyber agencies want migrations underway long before any breakthrough; NIST has finalized PQC standards and the UK’s NCSC has set a 2028–2035 migration window.
• For the bitcoin price, that means a communication challenge: outline a credible post-quantum plan and the market is less likely to price a “quantum discount.” Delay, and Edwards’ bearish scenario gains traction.
