Unless you are suggesting taxing crypto itself, in which case… sure!
In other words, the amount it takes in can be given back to the average person -- in forms of tax rebates, investment in public transit, education, whatever. In an ideal world a carbon tax would have no adverse impact on lower and middle class people.
I should also add that in that world higher electricity cost due to carbon tax is a good thing -- it'll help carbon-neutral sources of energy to compete and replace the more dirty forms. Which is exactly what we want.
But perhaps more importantly, you wouldn't be taxed because others are using electricity for virtual money. You would be taxed because your carbon emissions are causing climate change, and to encourage you to reduce energy usage where possible.

Also, you can make the tax progressive so that the high consumers can pay much more.
All money has a cost on society. You have to do something to maintain its value. You don't think wars in the middle east -- to maintain the petrodollar -- have an environmental impact?
And when it isn't oil it'll be fights over germanium and lithium veins.
If you actually cared to do more than sit in a chair -- advocating random things you didn't research -- you'd be advocating for Thorium power. Thorium is nearly as abundant as lead -- it's all over the place -- and it's much more clean and less dangerous than even solar or wind.
