Quantum threat framing shifts from mining to signatures and wallets

March 31, 2026Crypto Rover, Grayscale, Michaël van de Poppe

Grayscale, Crypto Rover, and Michaël van de Poppe argue quantum risk is primarily about signatures and wallet infrastructure rather than mining, pushing urgency around post quantum migration and quantum resistant wallets.

Most people think the threat is Bitcoin mining.
It’s not.
The real risk hits wallets, signatures, and key infrastructure first, which is exactly why post-quantum migration matters so much.
This doesn't lie in the mining, it lies in the signatures.
Post-quantum cryptography already exists
Samson Mow says quantum computing is not a near-term threat to Bitcoin.
Quantum Computing isn't a short-term threat.
