**Quantum Computing and Bitcoin: A Double-Edged Sword?**

Quantum computing advancements are stirring debate in the crypto world. While there's fear it might crack cryptographic codes, experts like Adam Back, Blockstream's CEO, see potential benefits for Bitcoin. He suggests future post-quantum signatures could bolster Bitcoin's security.

Google's new chip, Willow, has reignited concerns. It solves complex problems in minutes, a feat impossible for today's supercomputers. However, with only 105 qubits, it's far from threatening Bitcoin's encryption, which would need 13 million qubits for a breach. Ethereum's Vitalik Buterin is also prepping for a quantum future, proposing a hard fork to safeguard against potential threats.
