No. A quantum computer can't break a blockchain's ledger or the mining that secures it. The stored history stays right where it is. What a (capable enough) quantum computer one day will be able to break is the signature layer, the cryptography that decides who gets to move funds. That one distinction lurks behind every "quantum kills crypto" headline, and it changes what cryptocurrency holders need to worry about.

Sadly, Bitcoin isn’t quantum safe. The reason comes down to a specific piece of math. ECDSA (and Schnorr, for Taproot) over the secp256k1 curve authorizes every Bitcoin transaction, and Shor's algorithm dismantles both on a sufficiently large quantum computer. That's the short answer. As for the longer, more complicated one, it touches upon which coins are exposed, how migration would work, where the timeline sits, and what holders can do before the protocol catches up.

Quantum computing’s threat to crypto is the risk the market has, for the most part, blissfully ignored. But cryptographers and security researchers keep warning that a large enough fault-tolerant quantum computer will be able to break the encryption protecting almost all wallets on every major blockchain that relies on elliptic-curve signatures.
