The recent announcement of Google’s Willow quantum chip has rekindled concerns about quantum computing’s potential to undermine Bitcoin’s cryptographic security. For context, Google’s Willow quantum chip represents a major advancement in quantum computing technology.
With 105 qubits, Willow is a step forward in Google’s efforts to develop more powerful quantum processors. Quantum chips like Willow leverage the principles of quantum mechanics to perform computations far beyond the capability of traditional computers.
The development of this technology has now sparked fears among Bitcoin investors due to its potential implications for cryptocurrency security.
It is speculated that Willow could theoretically crack Bitcoin’s cryptographic algorithms (ECDSA and SHA-256), which safeguard private keys and transaction integrity.
Hackers could access funds or disrupt the blockchain’s security if these algorithms are compromised. However, Bernstein analysts have shared their outlook on this possibility.
Should You Worry?
According to a report by Bernstein analysts led by Gautam Chhugani, the practical risk to Bitcoin from quantum computing remains “decades away.”
However they pointed out that regardless of Willow’s 105 qubits, millions of qubits would be required to compromise Bitcoin’s Elliptic Curve Digital Signature Algorithm (ECDSA) and SHA-256 hashing protocol.
However, the report advises that Bitcoin contributors should proactively explore transitioning to quantum-resistant encryption to mitigate future risks.
Implementing such solutions could involve trade-offs, such as increasing storage and bandwidth requirements for node operators, potentially necessitating a network-wide hard fork or a gradual soft fork for users to migrate their coins.
Meanwhile, some industry experts shared a somewhat similar outlook. Charles Edwards, founder of Capriole Investments, suggested a 50% chance that quantum threats to cryptography could emerge within the next 5-10 years.
The level of Quantum Computing skepticism today reminds me of the average person who spends 10 minutes researching Bitcoin and then dismissing it as valueless.
Quantum Computing is real. It will change the world. MASSIVELY.
QC will break Bitcoin if we do not upgrade it. The…

He advocated for immediate action to address quantum vulnerabilities to ensure Bitcoin’s long-term resilience. Notably, beyond BTC, quantum computing poses potential risks to all cryptographic systems, including traditional banking and secure file storage.
Bitcoin Market Outlook
Amid the Willow saga, BTC has faced a notable plunge to as low as below $95,000 yesterday triggering more than $1 billion in total liquidations in the crypto market.
Bernstein analysts noted that the current price range of $95,000–$98,000 offers an attractive entry point for investors with a medium to long-term horizon.
The firm maintains its 12-month price target for Bitcoin at $200,000, citing strong demand from exchange-traded funds (ETFs) and corporate participants like MicroStrategy and major mining firms.
The analysts further urged investors to “stay long” and consider the recent price dip as a “buying opportunity,” given the positive market momentum driven by institutional demand.
Gautam Chhugani, one of Bernstein’s analysts, remarked that BTC might take a short “holiday breather” before breaking through the $100,000 level permanently.
