- Energy prices are getting more expensive as we can all see now, so for Bitcoin mining to be profitable bitcoin prices needs to go up otherwise it becomes unprofitable and miners will leave the bitcoin network making the bitcoin network less secure and vulnerable to 51% hack attacks correct?
As energy prices go up, hash rate will decline unless the price of a bitcoin increases faster than the price of energy. However, the hash rate is arbitrary. It is the cost of mining the provides the security.
- A drop in hash rate makes btc mining more easy attracting new miners to join the btc network to secure the network however what if the smart grid 2.0 detects and stops new bitcoin miners joining the btc network?
Would the "smart grid 2.0" just be in the U.S., or world-wide? It's hard to say what a world-wide ban on mining would do, or if it is likely or even possible.
- The governments around the world are pushing their agendas for to stop global warming and bringing up ESG regulations. When this time comes then how can bitcoin miners mine bitcoin off the grid?
Just like electric vehicles, Bitcoin gets its power from the electricity providers. It is up to these providers to decide whether or not to burn carbon. Bitcoin has no control over it.
- Energy/Power rationing is happening around the world now in many countries due to high energy rising costs where governments have to ration energy usage in their own countries to decide who gets the power. They allow essential hospitals and airports to get the electricity but what about bitcoin miners?
Rationing is about setting priorities. I doubt that Bitcoin would have any priority at this time in most places, so mining would probably be restricted in countries that are rationing. However, that doesn't prevent miners from moving to other countries (as they did when China banned mining).
