Hong Kong-based Cango Inc. has bought a 50-megawatt Bitcoin mining facility in the US state of Georgia for $19.5 million in cash. The company said the site will underpin a broader energy strategy and create additional hosting revenue as it expands beyond its core automobile services business. In a separate move, sources say US-listed Marathon Digital Holdings is in advanced negotiations to purchase a majority stake in Exaion, the cloud-and-blockchain subsidiary of Electricité de France, in a transaction that could be valued at roughly $168 million. Marathon is seeking to extend its reach into artificial-intelligence computing while reinforcing its position as the world’s largest publicly traded Bitcoin miner. The two transactions highlight accelerating consolidation and diversification in the cryptocurrency mining sector, where companies are accumulating power-intensive assets and new business lines to buffer returns against volatile coin prices and higher energy costs.
