You need to understand that if Bitcoin mining is going to lead to blackouts then obviously it’ll be outlawed, especially during peak times. Maybe allowing mining during nighttime should be allowed if laws like this pass.
But we don't even need all the Bitcoin miners that are running right now to be online anyways for Bitcoin to function at the same speed it is now, so seems like if laws do have to exist it would just limit amount of power each miner is allowed etc.
Still a shitty solution.
They could force a POS version of Bitcoin if the laws got too insane, but that would be another split.
