Lol, I have no issue with 24/7 mining because I don't even use grid anymore, I'm 100% running on solar panels for my home and my mining rigs, everyone will give their best to achieve what ever they aimed for and that's what Elon Musk is trying to do here, he pumped Dogecoin which is another PoW algorithm coin, it's clear that he is saying nonsense
it's a dirty play from them after switching to green source of energy they will just say we can use this energy for something useful , they want to destroy POW to crackdown the crypto security and then say see it's not secure enough
