Bitcoin Slumps as Quantum Computing Advances Threaten Blockchain Security

Bitcoin's price took a hit yesterday, dropping to around $63,000 following AT&T's breakthrough in quantum computing. Using D-Wave technology, the company managed to cut a complex network task from one hour to just 15 seconds. This advancement has brought the timeline for 'Q-Day,' when current blockchain encryption could be compromised by quantum computers, ever closer.

Experts warn that cryptocurrencies like Bitcoin face increased security risks as quantum power grows. Major tech firms are preparing for the development of cryptographically relevant quantum systems by 2029. The challenge now is whether Bitcoin's community can upgrade its encryption protocols in time to stay secure.
