Could Bitcoin be cracked in 2029 after Google just reduced its estimate of the number of qubits needed to break elliptic-curve cryptography by as much as 20 times?
Many people are worried about "Q-Day"—the point at which quantum computing could threaten the entire blockchain system. But from my perspective, the real threat to Bitcoin isn’t the cryptographic technology itself; it’s the decentralized governance mechanism.
Compare this: a traditional bank only needs a single decision from its board of directors to upgrade its security systems. Meanwhile, Bitcoin requires consensus from millions of miners, nodes, and developers across the globe. This upgrade process is extremely slow and prone to disagreements. If the network can’t reach consensus in time to move to post-quantum cryptography, the risk of being attacked is absolutely real.
This is a long-term risk, and the process will unfold gradually. Our job isn’t to panic, but to closely monitor how the Bitcoin community prepares for technology upgrades in the years ahead. Always manage portfolio risk and do thorough research before making any trading decisions.
