I stumbled upon a video on TikTok(link below) talking about a bathhouse business in New York using the heat from the Bitcoin mining rigs that they own to heat the water that they use for their pools. for anyone curious about the process of how they heat the water they use for their pools, they made a FAQ on their website about it, I'll share the link below.
obviously, there are people who don't like what they are doing because of the carbon emission produced by the Bitcoin mining rigs. but personally, I think this idea is genius, they are saving money for their business by using the heat from the mining rigs and they are earning money from mining Bitcoin, it's a win-win.
