No, it totally makes sense and it's something I've been thinking about a lot too.
The only problem is, why would Bitcoin miners set up the infrastructure to use Sahara solar or thermo from Finland when it's cheaper to just use Texas' cheap coal power? It's always going to be driven by the bottom line.
The main issue that I have is that all that computing power is being used on solving extremely difficult equations that don't matter. Surely there is a way to use all that computing power on something important to mine crypto?
