Bitcoin's Quantum Shield: A Concise 200-Word Overview
VICTORIA, Seychelles — December 17, 2025 — The cryptocurrency community is abuzz with discussions regarding the "Quantum Doomsday Clock." Financial expert Charles Edwards recently cautioned that unless Bitcoin enhances its encryption by March 2028, its value might fall beneath $50,000 due to the risks posed by quantum hacking.
What is the Danger?
At present, Bitcoin employs a digital signature (ECDSA) that is nearly unbreakable by modern computers. Nonetheless, specialists anticipate that by 2028, quantum computers from firms such as IBM or Google might achieve 1,673 logical qubits—sufficient capability to "determine" private keys and siphon off assets from outdated wallets.
The Strategy: Hash-Dependent Signatures (HDS)
Developers are not remaining inactive. Hash-Based Signatures are currently being tested, acting as a "quantum shield" that depends on simple, established mathematics instead of intricate elliptic curves.

The Conclusion: Bitcoin has endured all technical obstacles for 16 years. By transitioning to quantum-resistant addresses ahead of the 2028 deadline, the network aims to maintain its status as the "unbreakable" gold standard of the digital era.
