“An untraceable money exchange for these purposes.
Change my mind.”
Every transaction made with Bitcoin is traceable. You can know which wallet it came from, where it has been, etc. It is very traceable. Cash, OTOH, is not.
The naysayers keep repeating false information and you can’t tell them otherwise.
You can literally track everywhere it has been.
The only thing untraceable is the US dollar made to drug lords, terrorists, human traffickers, war lords, and gun runners.
