Considering that most countries are turning "green", it's likely PoW mining will be banned in the future. Maybe BTC will change its algo to something better than PoS without compromising decentralization?
and what would that something be exactly? isn't that the problem that there isn't really a good candidate for that? change bitcoin from Proof of Work and it really isn't bitcoin anymore. Because that would require a hard fork for sure.
I have witnessed it myself with all miners in Spain (big and small): back in 2017 the tax agency forced all miners to create a company or register as freelancers, which meant that they suddenly had to pay >300€/month regardless of their production just in order to be able to switch on their computer, plus between 25%-50% of their income in taxes every year. If we add the increase in the price of electricity to the equation, they simply killed Bitcoin mining in my country.
whether everyone obeys that new law is a different question though. you seem to think they do but i doubt it.
It is easy to expect that miners (at least the sizable ones) will leave the US in search of new countries with more favorable taxation. Obviously this could involve moving all the equipment to these countries
it depends. how do you move a oil field to another country? answer: you don't. you just pay up. or don't mine bitcoin.
and don't forget, just because you move out of the USA doesn't mean you don't have to pay income taxes to the USA unless you relinquish your American citizenship. that's just how it works. live where you want but you owe uncle Sam his taxes no matter where you live.
