We need to figure out how we will deal with the massive impost on the power grid ........ and saying it is renewable is not necessarily an answer. The other way to put it is, "bit coin mining is using up all our renewable...."
When you plug your hair-dryer in (I imagine Mark with long, luscious hair blowing in a stiff Seabreeze, gazing out to sea) it doesn't send a signal to the power station to produce more electricity.
etc.
A pool pump is about the equivalent of, say, a DragonMint 16T.

As you'll see you
need cheap electricity to be profitable; you're not adding to peak hour productivity because it's too expensive. A renewable source like hydro is
wasted at night because nobody is using it and it can't be stored, nor turned off. Ditto wind.
Look, it's not as good as zero electricity, but it's blown out of proportion because hyperbole and emotionally baited headlines. There's an argument at least that it is a lot, lot lighter on electricity than the current financial system
as a whole.
It could be better.
