Just ask chat gpt what happens to the formalism of QM/QC IF time is quantized and discrete. Ask it how it can take the derivative of time if there is an invisible tick. Ask it what becomes of superposition and decoherence if time has an indivisible tick. Just understand the assumption that backs the threat model, then you can decide what you believe. You can’t logically believe in both Bitcoin and QC, you must choose one as they require incompatible models of time.
