As quantum computing continues to evolve, questions about its potential impact on Bitcoin are gaining renewed attention. At the center of the debate is whether the world’s largest cryptocurrency could one day be vulnerable to the immense processing power of quantum machines. While the technology is still in its early stages, the discussion around long-term security is becoming increasingly relevant.
Amid the frenzy, crypto analyst Luke Martin has shared the only public comment Satoshi Nakamoto made about the quantum computing risk on Bitcoin. Martin revealed on X that in 2010, a user named llama raised concerns about what would happen if BTC cryptographic signatures were broken by quantum technology, and whether that could render BTC worthless.
What Satoshi Nakamoto Actually Said About Quantum Risk
Satoshi’s response acknowledged that a sudden breakthrough could pose a serious threat, and a gradual advancement in quantum computing would give the network time to adapt and transition to stronger cryptographic methods. He further explained that users could upgrade their software, and upon doing so, their holdings would be re-signed using a more secure algorithm.

The current narratives surrounding quantum computing as an imminent threat to Bitcoin are being overstated. An analyst known as pika2zero on X argued that the technology is still far from the level required to meaningfully challenge BTC’s cryptography, despite recent claims suggesting otherwise.
Pika2zero pointed out that the current most advanced quantum systems operate at around 6,000 qubits and can only be maintained for 13 seconds. In his view, this is nowhere near the scale needed to break modern encryption, which requires 500,000 stable qubits in 9 minutes, especially as the technology is getting exponentially harder.
Even minor disturbances are capable of collapsing the entire computation. However, he further questions the assumptions behind the Heisenberg Uncertainty Principle, suggesting that the real requirements for breaking modern cryptography could be millions of qubits, rather than the commonly cited estimates.
Building and operating such a machine to attack BTC would require massive resources, potentially only accessible to major technology firms like Google, IBM, or other Bigtech, and would demand enormous energy and infrastructure. From pika2zero’s perspective, an individual hackster can not have a $10 billion supercomputer the size of a building and the energy demand of a small city in his basement to attack BTC.
Will Bitcoin Adopt Stronger Quantum Defenses In Time?
Senior analyst at CoinDesk and advisor at Coinsilium Group, James Van Straten, has also offered insight into BIP 360 as a short-term solution for quantum resistance. However, it will not address the full scope of the problem. Van Straten argues that using quantum computing to access Patoshi’s coins is estimated at around 1 million BTC and could be considered a fair game.
At the same time, he points to alternative approaches such as Hourglass V2. James noted that the market had previously demonstrated its ability to absorb significant selling pressure and handle close to 1 million BTC over 30 days in December without systemic disruption.
