Thank you all for discussing on this topic. So, as many of you have stated that countries/cities are not banning Bitcoin mining, but some are encouraging. That is true, but as
@Za1n gave the example of Plattsburgh, this is also worth noting. Many smaller cities with cheaper electricity are not able to meet the demands. Which leads to less electricity available for their own residents and increase in electric bills. And to mitigate this, miners are told to either pay more per unit of electricity or leave. And that has nothing to do with those cities being in favour or against the Bitcoin itself.
Pursuing I hope you understand that I am not saying some cities banning mining is related to lesser profits. I am just saying that options become less for miners. Say for example Iceland. Currently it is estimated that 50% of their electricity is consumed in Bitcoin mining. And that is a very big amount. What happens when the electricity demands for Bitcoin mining keeps increasing but the rate of generation of electricity does not match. Then those govts. are obviously forced to give much higher electricity bills to the miners. That's where the unprofitability part comes. Of course, long term miners can absorb losses in order to stay in the competition and hope for price increase in future to compensate for the losses. But that obviously introduces centralization. Not necessarily a bad thing, but not very comforting also. Especially when you learn that country wise Chinese and Russians will have upper hand in Bitcoin mining!
Herbert2020 you mentioned many articles which state that countries are welcoming miners. If true, then this is of course an excellent thing.
And for people stating that large IT companies also eat up a large chunk of electricity and lead to increase in prices. That is fully true, but the thing is that they are providing a lot of jobs, taxes, expertise, overall economy growth. This is what I state from the viewpoint of govts. or non-crypto people. They see IT companies bringing something in and Bitcoin mining as basically a speculative thing not benefiting their country much. So when the electricity demands reaches out of control, who do you think they will favour? IT companies or Bitcoin mining?
*This above paragraph is fromt he viewpoint of govts. or non crypto people. As a crypto enthusiast, I of course do realize that Bitcoin mining is not wasting the energy. But ya certainly it might help a lot if somehow the electricity consumption in Bitcoin mining can be brought down.
Between I think if current Bitcoin miners can add their opinions on this topic, then it would be highly appreciated. How long do you think you can handle the increased mining costs before you quit?
Edit: OK, I have to admit one thing that I just understood. That is, the mining difficulty does not necessarily increase, in fact it depends more on how many competitors are there at a given time. I was seeing the charts with clear increasing difficulty rates and I assumed that it only increases as time passes.
