In a recent update from October 2026, Coinbase (NASDAQ: COIN | COIN Price Prediction) shared that it could take years to make Bitcoin (CRYPTO: BTC) ready for post-quantum cryptography. This raises a critical question for Bitcoin holders: Is your Bitcoin safe from quantum computers in the meantime? Post-quantum cryptography refers to security measures designed to withstand future quantum computing threats.

Currently, a quantum computer capable of cracking Bitcoin’s cryptography has not been constructed. However, Coinbase is taking proactive measures because these upgrades require significant lead time. The company is advocating for flexible designs that can adapt as quantum-resistant techniques are developed. It’s important to note that Coinbase can only recommend changes; any actual updates to Bitcoin require consensus among developers, miners, and the users who run its software.
