Bitcoin’s price has dropped sharply, falling below $70,000, as investors grow nervous about new risks to the cryptocurrency. The price has been struggling
ever since it fell from its peak of $126,000 in October last year. Recently, fresh speculation about the identity of Bitcoin’s mysterious creator Satoshi Nakamoto has added to the uncertainty. Now, concerns have intensified after warnings from BlackRock and comments from Elon Musk. The fears are linked to new developments in quantum computing (a powerful next-generation computing technology that can solve complex problems much faster than today’s computers). Musk reacted to the situation on X (formerly Twitter), saying: "On the plus side, if you forgot the password to your wallet, it will be accessible in the future."

He shared this alongside a response from his chatbot Grok, which warned that updating cryptocurrencies to resist quantum attacks is now urgent.

These fears grew after a venture capitalist, Max Reiff, summed up new research from Google in simple terms: “basically saying: ‘We’ve cut the quantum resources needed to break bitcoin’s encryption by 20x. We can now break it. We can prove it. We’re just not going to tell you how. We’ve slowed down research to give crypto a chance. You have until 2029 to figure out a solution. Good luck.’”
What does this mean?
Bitcoin is protected by encryption (a method that keeps data and transactions secure using complex math). Normally, it would take today’s computers an extremely long time to break this security. But quantum computers could potentially crack it much faster.
According to analysis from Project Eleven (a group studying quantum risks), about 7 million bitcoins - worth roughly $470 billion - could be at risk if this technology becomes powerful enough.
Chris Tam from BTQ Technologies said, “This is the clearest signal yet that cryptographically relevant quantum computing is approaching faster than many expected. When a company like Google commits to a timeline like this, the industry should take notice."
Earlier this week, Google’s Quantum AI team said that the number of qubits (the basic units of quantum computers, similar to bits in regular computers but far more powerful) needed to break Bitcoin’s security could be up to 20 times lower than previously thought.
Heather Adkins, Google’s vice president of security engineering, wrote, “We’re setting a timeline for post-quantum cryptography migration to 2029.”
“Quantum computers will pose a significant threat to current cryptographic standards, and specifically to encryption and digital signatures.”
Investor Nic Carter compared the situation to the Manhattan Project, the secret US program that developed nuclear weapons, suggesting the potential impact of quantum computing could be just as transformative and disruptive.
