Quantum breaking BTC!

No.

It would required 2400 Shor compliant Logical Qubits with error correction of 10^-12, with all qubits working in perfectly symphony with no decoherence. Also each shor logical qubit should use around 8000 physical qubits for a grand total of 18 million physical qubits.

So far we haven't even created 1 such Shor compliant logical Qubit.

The best we've done so far is 2 logical qubits using 50-100 physical qubits with an error correction of only 10^-3.

Which means we are at least 10 years away from creating a single Shor compliant logical qubit required to break ECDSA. Let alone 2400 working in perfectly symphony.

And even if we do, there are many ways to upgrade to quantum resistant addresses.
