Google slashes quantum cracking estimates by 20X creating $600 billion countdown for Bitcoin and Ethereum
Google used zero-knowledge proofs to verify quantum attack estimates without exposing the underlying attack circuits.

As quantum ‘Q-Day’ jumps to 2029, Ethereum faces a new fight over what to do with coins left in old wallets
The Ethereum Foundation’s post-quantum roadmap argues that the real danger is a years-long struggle over how to move user wallets.

Bitcoin may tumble toward $30,000 next year unless it shows real progress toward quantum proof upgrades
Bitcoin faces pressure to upgrade with warnings of a steep price discount sparked by quantum computing risks.

This “quantum-safe” Bitcoin idea removes Taproot’s key-path — and raises fees on purpose
If it ever activates, it’s opt-in and slow, because Bitcoin’s real constraint is coordination, not cryptography.

Ethereum’s massive fee shock: New post-quantum signatures are 40x larger, threatening to crush network throughput and user costs
Coinbase, Solana, Polkadot, and Bitcoin all moved on PQ planning, but wallet UX and aggregation may decide the winner.
Quantum
Bitcoin’s “quantum” death sentence is causing a Wall Street rift, but the fix is already hidden in the code
The quantum computing threat challenges Bitcoin's status as "digital gold," prompting strategic shifts.

Bitcoin encryption isn’t at risk from quantum computers for one simple reason: it doesn’t actually exist
There are no secret messages on the blockchain to decrypt. The real threat is Shor’s algorithm forging signatures on keys you’ve already revealed.
Quantum
Michael Saylor says quantum will “harden” Bitcoin, but he’s ignoring the 1.7 million coins already at risk
Shor breaks ECDSA/Schnorr at scale, while Taproot pubkeys are already visible. NIST’s PQC path and an Optech draft show how Bitcoin could migrate without panic.
