Quantum leap in the crypto world: Is Bitcoin threatened with extinction?

On October 23, 2025, there were significant developments in quantum computing technology that bring both opportunities and risks for Bitcoin and other cryptocurrencies. A recent report from Crypto News highlights that shares of companies involved in quantum computing rose following reports of possible investments by the Trump administration in large firms. This news followed a breakthrough announced by Google in quantum computing research.

Google unveiled a new quantum algorithm called Quantum Echoes that is capable of simulating molecular and chemical structures 13,000 times faster than traditional supercomputers. These developments could not only spur advances in various fields such as medicine and artificial intelligence, but also threaten technology that relies on blockchain and cryptography.

Threats to Blockchain Technologies

The narrative surrounding quantum computing raises new questions about the security of Bitcoin. Quantum News reports that upcoming advances in quantum computing technology could potentially make brute-force attacks on blockchain systems possible. This could particularly make proof-of-work networks like Bitcoin and Monero vulnerable to 51% attacks as the cost of solving cryptographic equations drops.

In addition, a large-scale attack on crypto wallets could significantly undermine trust in blockchain technology. David Carvalho of Naoris Protocol emphasizes that hackers and state actors are already preparing to exploit the weaknesses that quantum computing can create.

Current inventory risks and future outlook

Although the power of quantum computers is currently not enough to crack Bitcoin wallets - and may not be enough in the next decade - the increasing focus on quantum computing could create a negative narrative for blockchain technology. The positive market reaction triggered by the rise of quantum stocks could be misleading if the long-term risks are not recognized.

All of the stocks mentioned, including IonQ, Rigetti and D-Wave, saw significant gains on October 23 as news of possible government involvement broke. Nevertheless, it remains to be seen how these developments will affect blockchain technologies, especially Bitcoin, in the long term.
