Wouldn't people just use a quantum computer to simply generate an encryption that wasn't easy to break? Like we did when 64-bit computing came along. The principal of a two-way handshake seems solid, all you need to do is generate an encryption that is beyond whatever technology can brute force attack. So we might see something crazy like 64GB encryption, rather than 128Bit.

But that'd be impossible for Bitcoin since the vulnerable blockchain is already out there. I assume that before any quantum computer is released, that the people behind it will give the world time to adapt before they release the thing, otherwise it's gonna be a meteor impact on everything.
You should move to a communist country sounds like you hate freedom and love for the commie to protect, regulate and @$@#$@# you which you probably descrve . Freedom is not for people like you nor is BTC so take a hike!
