I hope you are all well. Today I got some exciting (or a bit shocking) news that I would like to share with you. As you all know, I always try to keep you upbeat and excited.

Imagine a computer so powerful that it could quietly hack into Bitcoin — and no one would even notice.
That’s what some experts believe could happen if a real quantum computer capable of breaking modern encryption came online today.

According to David Carvalho, CEO of Naoris Protocol, such a machine could take control of Bitcoin wallets while everything on the blockchain looked perfectly normal. “When you think you’re seeing a quantum computer, it’s already been in control for months,” he said in an interview with.

The concern isn’t science fiction anymore. Big players like IBM and Google are racing to develop quantum systems, while the U.S. National Institute of Standards and Technology (NIST) has already started approving new “post-quantum” algorithms to stay ahead of the threat.

For now, it’s still a theoretical risk. But if it ever became real, Bitcoin’s defenses could crumble before the network had time to react.

How Quantum Tech Could Break Bitcoin’s Security

Bitcoin’s entire security model relies on the Elliptic Curve Digital Signature Algorithm (ECDSA) — a cryptographic method designed back in 1985. It uses private and public keys to verify ownership of coins.

But with Shor’s algorithm, a powerful enough quantum computer could figure out private keys just by analyzing public ones. That means any exposed wallet, including some from Bitcoin’s early days, could be completely vulnerable.

“If that happened, no one could even prove it was a hack,” Carvalho warned. “The coins would just move like the owner decided to spend them.”

Kapil Dhiman, founder of Quranium, a blockchain project focused on post-quantum security, added that the oldest wallets would likely be the first targets.
“Satoshi’s coins would be sitting ducks,” he said. “If those move, confidence in Bitcoin would collapse long before the system itself fails.”

Traditional Finance Is Ahead of Crypto

While the crypto industry is still using encryption methods from the 1980s, traditional financial institutions are already testing quantum-safe systems.

Banks like JPMorgan and companies like SWIFT have started testing post-quantum networks. NIST has also approved new encryption algorithms designed to resist quantum attacks.

Carvalho says that’s partly because banks can upgrade faster. “Traditional finance has budgets and a single authority that can push updates. Crypto doesn’t have that. Everything needs consensus,” he explained.

What Happens If Bitcoin Fails the Quantum Test?

The biggest threat might not be the hack itself — it’s the loss of confidence.
If people start believing Bitcoin can be cracked, its price could crash and shake global markets that are increasingly tied to crypto.

Carvalho mentioned that while the risk isn’t zero, there’s no public evidence of a working quantum computer that can break Bitcoin-level encryption yet. But he compared the situation to the Enigma cipher from World War II — which was secretly broken long before anyone knew.

“When you think you’re seeing a quantum computer, it’s already been in control for months,” he warned again.

Still, experts remain hopeful. Dhiman said, “Quantum-secure systems are possible. We just need to start building them before the threat becomes real.”

For now, Bitcoin’s encryption remains strong — and quantum computers that could break it exist only on paper.
