I think it is not a complete ban in USA because i am also watching crypto news US government is regulate the Bitcoin mining it is just a electricity issues in US government. So these kind of problems are not affect the crypto market again all the cryptocurrencies are going to pump in next week.
Of course it's not a complete ban. Read the article, it's just about Plattsburgh.
And it's not a real ban against mining, more against industrial scale mining.
I think this is actually a positive development, bitcoin price might go up if operating cost of mining will go up with increase in electricity cost. When all mining farms situated at locations with cheap electricity will go offline it will be not profitable to other small scaled miners who are paying high electricity fee to sell their mined coins at lower price.
As much as I dislike FUD, let's not try to paint the situation pink cause it's not.
There is nothing positive about the news. It's not it's like the end of the world but I fail to see anything good coming out of this.
Also, your second sentence makes no sense, I see no relation between miners quitting and other forced to sell at lower price, because?? The bitcoin price has nothing to do with mining.
