From what I understand, Willow's 105 qubits still aren't enough to crack bitcoin's encryption which would require millions of qubits.
The fact that the crypto community has already anticipated this and is working on quantum-reistant solutions is reassuring.Post-quantum cryptography is already being explored to ensure bitcoin and other blockchains stay secure as quantum technology advances
As it was said - even if it would happen, it wouldn't target only BTC.
And BTC would be probably ready for it by that time.
If not - there will be a little breach, and then - the problem will be solved.
No in-between.
