Quantum Threat Looms: Why Bitcoin and Ethereum Remain Vulnerable in 2025
Quantum computers could crack crypto's security—and top chains aren't prepared. Here's why the ticking clock matters more than ever.
The Encryption Time Bomb
Most blockchain networks rely on elliptic-curve cryptography, the same tech quantum processors can theoretically obliterate. Bitcoin's SHA-256 and Ethereum's Keccak-256 hashes? Potentially child's play for a 1,000+ qubit machine.
Post-Quantum Hype vs. Reality
While 'quantum-resistant' coins tout upgrades, the big two drag their feet. Core devs argue practical attacks remain years away—conveniently ignoring that Wall Street's quantum arms race just hit overdrive.
The Institutional Blind Spot
VCs keep pouring billions into DeFi projects with 20th-century security. Nothing says 'forward-thinking investment' like betting against Moore's Law.
Wake-up call: When the first quantum breach hits, 'HODL' won't save your cold wallet.
