Crypto markets have always faced cycles of hype and correction, but a new kind of threat could change everything – quantum computing. As this technology advances rapidly, experts warn that it could soon challenge the very cryptography that keeps Bitcoin and other cryptocurrencies secure. Is the threat as big as it sounds? Let’s explore.
Bitcoin Bear Market Coming Soon?
Crypto analyst Charles Edwards says that he once believed that future Bitcoin bear markets would become milder over time as markets mature. But now, he warns that if the quantum threat is not addressed soon, possibly as early as next year, Bitcoin could face its biggest bear market ever.
At the Token 2049 event, Edwards discussed the current state of Bitcoin and crypto, highlighting two major threats to the market: treasury exposure and the growing power of quantum computing.
What is the Quantum Threat to Bitcoin Security?
Edwards explained that within 2–8 years, advanced quantum machines might break Bitcoin’s current elliptic curve encryption, leading to dire ramifications. Imagine if Satoshi’s coins, which have been dormant for years, suddenly flooded the market, drastically impacting Bitcoin’s value.
Major tech companies like AWS, Google, Azure, Microsoft, IBM, and Meta are already deploying quantum systems, with governments investing billions to gain an edge. For instance, China is reportedly spending twice as much as the U.S., committing a whopping $55 billion to the quantum industry recently.
Q-Day Could Be Closer Than Expected
Multiple credible sources, including McKinsey, predict that “Q-Day” — the day when quantum computers could break classical encryption — could arrive within the next 2 to 10 years. Furthermore, Bitcoin’s elliptic curve cryptography is weaker than RSA encryption, making it potentially vulnerable even sooner than these estimates suggest.
According to the 2017 Bitcoin Quantum Paper, only around 2,300 logical qubits would be required to compromise Bitcoin’s encryption. Notably, Vitalik Buterin, the co-founder of Ethereum, estimates a 20% chance that quantum computers could undermine cryptographic systems by 2030.
Upgrading the Bitcoin network to quantum-secure wallets could take between six months to a year. This necessitates proactive planning and development, with some experts advocating for 2026 as the target year to begin these crucial upgrades to mitigate risk.
What Can You Do?
In light of these challenges, Edwards encourages the crypto community to engage with Bitcoin Improvement Proposals (BIPs), advocate for necessary upgrades, and raise awareness about the quantum threat. If swift action is not taken, the crypto ecosystem could face significant turmoil, potentially jeopardizing Bitcoin’s future.
