Marathon Digital Holdings has launched a pilot project in Finland to use waste from Bitcoin mining to heat the homes of 11,000 residents. 🏘️ As part of the 2 megawatt project, the heat released during mining is recycled and used for centralized water heating. This could be a promising heating method given the significant amount of excess heat that Bitcoin mining rigs produce. Marathon is the world's largest Bitcoin mining company, valued at over $5.84 billion.
