Quantum computing is still extremely far from cracking Bitcoin.

Shaw, in an article on the X platform, stated that there is a huge gap between the actual progress of quantum computing and media hype and public perception. Despite progress in the field, quantum computers will not achieve their claimed capabilities within the next 40 to 50 years. For hash functions like SHA-256, even with the most ideal Grover algorithm, the search space can only be reduced from 2 to the power of 256 to 2 to the power of 128, which is still physically unbreakable. Shaw pointed out that even the most advanced quantum computers cannot factor the number 21 into 3 and 7 without knowing the outcome. To crack Bitcoin, a quantum computer would have to repeatedly compute on the real-time network within minutes, a leap far exceeding the advancement from computers in the 1950s to modern server clusters. Modern cryptography was designed with future computing power growth in mind. Current fears or hype surrounding quantum computing lack factual basis.
