Re: I don't believe Quantum Computing will ever threaten Bitcoin
Great's to read OP,
This is what you think !
Now can you imagine if certains parties wants to targets someone, there is simply just nothing that he can do. Do this is not a field that discourage the using of Bitcoin !?
And here's is the question, as there's already Quantum-Proof cryptocurrencies existing.

What do you think of a graduated upgrade that could implement the core/network with a protocol using a second private key for an address, so the core recognise if a address is upgraded to/(have adopted the protocol), and then alow or not the task from that address. As that's would be operated gradually, from a proper adoption of the wallets owners, anybody will forgotten!

If someone wants to help Bitcoin against the future threat of quantum computers it would be contributing to the projects which are intending on implementing the quantum resistant algorithms or Bitcoin itself.
I know that we are far away from that reality but preventing the possible QC attacks to the network is more viable. I'm just not sure how they are going to do it because knowing the computing capabilities of QC, and it could outsmart any problems faster than normal.
