Well, most who live in Bitcoin friendly countries reap the most benefits because it takes a lot less to pay the hydro bill.
Those living in Bitcoin hell may be left behind and may unplug once it becomes unprofitable, before it ruins them.
It's called political extortion of public wealth.
Many countries don't allow citizens to own solid Gold; many also have a strong stance against it.
Forbid real wealth of any kind in the hands of the people; such as precious metals, property, real estate and other value gaining assets.
It's that or they make it really unprofitable or painful to acquire.
I used to sell Gold and many countries don't accept it at all or severely tax it; India is over 40% I believe for citizens but the government buys TONS!!
Eventually, the most money will be made in power saving and free energy devices.
I bet a 5KW/h free generator that cost little to nothing to operate will outsell any miner 10 to 1.
As one said, mining is way over saturated but many "old timers" have stopped re-investing because they owe too much or just already made their fortune.
A new generation of miners is needed but that is heavily dependent on where you live and living arrangements.
Welcome aboard!
