As Bitcoin navigates severe macroeconomic headwinds—trading near $68,800 amid intense global geopolitical friction and recent price pullbacks—a longer-term, more existential specter continues to loom over the industry: quantum computing. For years, the narrative has been that a cryptographically relevant quantum computer (CRQC) could instantly break Bitcoin’s encryption, triggering a “Q-Day” apocalypse. However, a comprehensive new research report from Galaxy Digital fundamentally flips this script. The quantum threat is real, but Bitcoin is already fighting back.

The $470 Billion Target: What Is Actually At Risk?
Galaxy Research, spearheaded by analyst Will Owens and Head of Research Alex Thorn, cuts through the market hysteria with a sobering reality check. A quantum computer does not magically drain the entire Bitcoin network at once. Instead, the threat relies on the machine’s ability to derive a private key from a known public key.
Because of this mathematical constraint, not all Bitcoin is equally vulnerable. The immediate danger is isolated to “long exposure” coins. These are wallets where the public keys are already permanently visible on-chain.
According to data cited by Galaxy from Project Eleven, roughly 7 million BTC—valued at over $470 billion at current pricing—falls into this high-risk category. The most vulnerable assets include:
- Legacy P2PK (Pay-to-Public-Key) Outputs: Relics from Bitcoin’s earliest days, including untouched, dormant coins mined by Satoshi Nakamoto.
- Reused Addresses: Wallets where users have repeatedly sent and received funds, inadvertently exposing their public keys in the process.
- Certain Custodial Wallets: Exchanges or institutional entities employing outdated operational practices.
The Built-In Shield: Why Your Modern Wallet is Likely Safe
If you are holding BTC in a modern, properly managed wallet, you can take a collective breath. Bitcoin’s Unspent Transaction Output (UTXO) model provides a natural, structural buffer against immediate quantum decryption.
Most modern wallets do not expose the public key until the exact moment a transaction is broadcast and spent. Until that split-second broadcast, the network only sees a cryptographic hash of the public key. Current quantum theory suggests that breaking a hashed address is exponentially more difficult—putting standard wallets out of the immediate danger zone of early-stage quantum hardware.
Developers Are Racing the Clock: Enter BIP 360
The most persistent piece of FUD (Fear, Uncertainty, and Doubt) in the market is that Bitcoin Core developers are asleep at the wheel. Galaxy’s report aggressively debunks this. The ecosystem is actively laying the technical groundwork for post-quantum security.
The tip of the spear is Bitcoin Improvement Proposal 360 (BIP 360). This leading soft-fork proposal introduces an output type called “Pay-to-Merkle-Root” (P2MR). If integrated, this upgrade would allow the network to maintain all the advanced smart-contract capabilities of Taproot while permanently eliminating the flaws that expose public keys to quantum derivation.
Adding concrete momentum to this narrative, BTQ Technologies recently launched the first fully functional implementation of BIP 360 on a live testnet. This allows miners, node operators, and researchers to pressure-test quantum-resistant transactions in real time. Also on the table are “Hourglass” mechanisms designed to throttle the speed at which exposed legacy coins could be drained during a worst-case scenario.
The Real Bottleneck is Governance, Not Tech
If technological solutions exist, what is the hold-up? As a 10-year veteran of this market, I can tell you the true friction point: Bitcoin’s decentralized governance.
Bitcoin has no CEO, no board of directors, and no centralized mechanism to mandate a swift security patch. Major network upgrades like SegWit and Taproot took between 7.5 and 8.5 years from conception to final implementation. Galaxy rightly points out that this sluggish governance is exactly why preparation must begin today. We do not have the luxury of waiting for IBM or Google to announce a functioning CRQC before reaching network consensus.
Final Takeaway
Bitcoin price current $68k price tag is dictated by macro events, but its future survival depends on cryptography. The quantum threat is no longer a fringe theory. However, thanks to accelerating developer action and proactive frameworks like BIP 360, Bitcoin is proving it will not go down without a cryptographic fight.
