I too have considered this possibility. It is possible that with a strong enough quantum computer. Bitcoin would be an historical rug pull that would be used to implement stablecoins for dominance.
That is why I hope for the best. Prepare for the worst. That is why 50/50 is the way to go.
50% Income and savings dedicated to Bitcoin.
50% Income and savings dedicated to physical precious metals. Like gold, silver, platinum, palladium, and copper.
That way whichever way this coin of fate gets tossed. I am still going to be alright with the outcome. I wont loose everything of value.
At least I can say I put my faith into the only sound currency I believe in.
If that turns out to be a mistake. So be it.
I am at peace with this decision.
