Are you sure that Venezuela government isn't going to use these devices to mine bitcoin for themselves? The possibility is very strong because this country is struggling with hyperinflation since a long time now and they must find new sources of income as US barred them from selling oil.
It's quite unfortunate to see such a crackdown! But I believe if the miners can find an alternate source of electricity through solar panels or hydro powers, the environmental impact will be greatly reduced and the dependency on the national power grid will be zeroed down. But it's easier said than done!
