I slightly dislike(I know, I can be petty) those Twitter people who seems to think that Bitcoin is the answer to literally whatever news-trending problem there is. But "wasted" renewable energy is one good use-case of Bitcoin mining. They contribute to the network, and at the same time they get value in exchange for the supposedly wasted energy. Win-win!
Not only twitter, I think I have an obsessed friend who can't say a word without digressing his to go Bitcoin, always up for anything, when Bitcoin drops he would be like I knew it was just another scam, if it rises he would be like do you best to get as many Bitcoin like him, have come to see him as another real life influencers I am experiencing, they won't to be their in the midst of it, want to be seen as knowledgeable.
