The long-dreaded quantum computing threat to bitcoin isn’t a distant sci-fi scenario anymore—it’s knocking on our door in 2025. Security expert David Carvalho warns that 6-7 million BTC (stored in vulnerable wallets) could be harvested now and cracked later by quantum-capable entities. While solutions like BIP-360 and Taproot addresses exist, market inertia poses the real risk. Here’s why this silent crisis demands action today, not tomorrow.
Is Bitcoin Really Vulnerable to Quantum Attacks Right Now?
We’ve all heard the "future problem" narrative—that quantum decryption might threaten Bitcoin by 2045. But Carvalho’s July 2025 report hits differently: "Not tomorrow. Today." Governments and hackers are alreadyfrom the blockchain, waiting for quantum machines to mature. Imagine them stockpiling digital locks to pick later—a slow-motion heist in progress.
Which Bitcoin Wallets Are Most at Risk?
Not all addresses are equal. Legacy formats like P2PK and P2PKH (pre-SegWit) are sitting ducks—their ECDSA signatures crumble against Shor’s algorithm. Taproot upgrades help, but Carvalho estimates(per CoinMarketCap data) still use vulnerable setups. The irony? These are often long-term "HODLer" wallets, quietly accumulating risk.
Why 20 Years Just Shrunk to Maybe 5
Carvalho’s timeline revision sent shockwaves. Google’s 72-qubit processor and IBM’s "Quantum Heron" breakthroughs suggest we’re closer to cracking ECDSA than anyone guessed. Pair that withstrategies, and suddenly, "theoretical risk" feels like a countdown. Remember when we laughed at Y2K prep? This isn’t that.
What Can You Do Today?
1.: BIP-360-compliant wallets (like BTCC’s latest update) use lattice-based cryptography.
2.: P2WPKH and Taproot (P2TR) are your friends.
3.: Their decentralized quantum security mesh could redefine trust.

The Invisible Countdown
This isn’t FUD—it’s physics. As the BTCC research team notes: "Quantum advantage doesn’t need to be perfect; it just needs to beto break ECDSA." Waiting for visible cracks means acting too late. Think of it like pandemic prep: by the time hospitals overflow, the virus has already won.
Conclusion: Time to Future-Proof
Bitcoin survived Mt. Gox and bear markets. Quantum risk? That’s a whole new beast. The fix exists, but apathy is the real enemy. As Carvalho puts it: "Build the damthe flood." Because in this game, the early mover doesn’t just survive—they inherit the blockchain.
FAQs: Quantum Threats to Bitcoin
How soon could quantum computers break Bitcoin?
Carvalho’s 2025 report suggests ECDSA could fall within 5-10 years, not the previously assumed 20+ years, due to accelerated quantum advancements.
Which wallets should I avoid?
Legacy P2PK/P2PKH addresses using ECDSA signatures. Check your wallet provider’s documentation—most now label quantum-resistant options clearly.
Is my exchange account safe?
Exchanges like BTCC typically manage keys internally, but long-term storage in non-upgraded wallets remains risky. Always verify their quantum readiness.
