The good families of PA are already safe using conventional power providers with no poisonous waste coal responsibilities. The bitcoin mining contracts relieve them of the additional expense disposing of the waste coal. How anyone could possibly imagine bitcoin miners cheating the rate payers in this business arrangement is beyond comprehension but is a great example of how bitcoin haytrehd interferes with reasoning ability.If you want to make stuff up, I'd say I would keep the good families of PA safe by insisting their electricity plants are owned and operated by people with long track records of doing so safely.
If those sober, responsible, non-fly-by-night operators want to sell electricity to miners, that's between them and whatever regulatory bodies may exist.
I'd also add that when a new party appears offering to "clean up waste coal" or any similarly difficult civic matter at a price & terms that no more established & respectable operators can meet, I'd say that when a deal seems too good to be true, it often is.
