Quantum computing is coming? Bitcoin's quantum-resistant upgrade may become a catalyst for supply tightening
【Crypto World】Will the large-scale application of quantum computing truly threaten the security of Bitcoin? Michael Saylor’s recent viewpoint is quite interesting—he directly positions quantum computing as a booster for Bitcoin.
His logic is as follows: once the quantum threat truly emerges, the world will inevitably be forced to adopt quantum-resistant encryption technology. What does this mean? Users will need to migrate their Bitcoin to new addresses. It sounds manageable, but the consequences are quite subtle.
What will happen during this upgrade process—those long-unused Bitcoin addresses will be locked, and truly lost Bitcoins (with private keys destroyed or lost) will completely exit circulation. From a market perspective, this can effectively reduce the circulating supply. Saylor predicts that the available supply could shrink to about 16 million coins—compared to the current cap of 21 million, this is a significant tightening.
Looking at it from another angle, this technological upgrade is both a risk and an opportunity for supply-side reform. Of course, all of this depends on when quantum-resistant technology truly becomes a necessity.
