The akashic records kind of make securing Bitcoin against quantum computing, impossible.
I don't think it matters though. By the time we're get there we're transitioning into the fourth & fifth densities at scale. There are no secrets, no ability to hide anything.
This is the era of the quantum financial system (QFS).
Note: if you look into the QFS, you'll find a whole heap of garbage & noise. I believe Bitcoin will eventually either be replaced by it or transition into it though. Right now it is beyond our comprehension as to how it could function.
