learn about Bitcoin Multisig security and then you tell me how long it will take

  No present security will be suficient once IBM or others breaksthrough with Quantum. This will happen for sure. https://www.youtube.com/watch?v=I20KgRZCZEI https://www.youtube.com/watch?v=I20KgRZCZEI

    There's no guarantees that breakthrough is coming anytime soon. Scaling up the number of qubits in a processor is very hard and it's why progress has been pretty slow over the last decade.

      Crypto is your guarantee that a quantum breakthrough has not already occurred

        Not 100% sure what you mean but it depends on who makes it. A government would have better things to do with an encryption destroying quantum computer than crashing blockchains. Personally I wouldn't crash crypto coins immediately, I'd make some money off them first then wipe it out. Also I was talking about the future. It may be impractical for centuries to make a quantum computer large enough to factor large current cryptographic keys. Last I read the difficulty of maintaining coherence has a non linear relation to the number of qubits involved.

    Unclear this will "happen for sure", but even if it did there are quantum-proof encryption techniques
