Quantum computers pose EXTRA risk to PoS chains over Bitcoin, per Coinbase's advisory board.
Key findings:
BTC's mining hash functions = safe from quantum attacks
PoS validator signatures = additional vulnerability layer
While everyone panics about quantum breaking BTC, the real exposure might be in your staked ETH/SOL positions. PoS relies on digital signatures that are MORE susceptible to quantum decryption than PoW's hash-based security.
This isn't theoretical FUD. Institutional advisors are flagging this NOW.
If you're heavy in PoS alts, understand the tech stack. Quantum-resistant upgrades aren't here yet for most chains.
BTC maxis might actually have a point this time.
