They provide a legitimate demand response service i.e. when the grid is generating excess energy that there's no other demand for, Bitcoin miners buy what no one else wants/needs.
Texas has a lot of gas plants (51%) that we want to idle when possible. Just because it's cheaper power doesn't mean we should be generating it when the only customer is cryptocoins.
If the cost of gas isn’t covering the actual impact then the cost should be higher, doesn’t matter if the kWh is used by a bitcoin miner or someone with their AC at 70, it’s still the same externality.
I think it’s pretty easy to understand that what amounts to a game isn’t even vaguely comparable to something that provides an immediate and quantifiable impact for someone. Perhaps you don’t understand that bitcoin is a leech on society with no real benefit.
The reality is that fiat is the leech on society. It's a cancer on the world, slowly destroying it. Bitcoin is the cure. It's one of the most important inventions in the history of mankind and it's positive effects on the world will be profound. I'd go as far as saying that it's more important than the internet itself.
Watch some Michael Saylor/Robert Breedlove interviews and educate yourself. Read "The Creature From Jekyll Island".
Thank God Texas generates power from unlimited resources. In my place, the more we generate and consume, the less we have left for the future. In Texas, the plants have to generate as much as possible for some reason !
Buyers of first and last resort.
