The U.S. Securities and Exchange Commission (SEC) has approved the listing and trading of Bitcoin and Ethereum exchange-traded funds (ETFs) from Hashdex and Franklin Templeton. The newly authorized Hashdex Nasdaq Crypto Index US ETF and Franklin Crypto Index ETF will initially hold spot Bitcoin (BTC) and Ethereum (ETH). This approval marks a notable development in the cryptocurrency investment landscape, as both firms plan to expand their offerings to include additional cryptocurrencies in the future, pending regulatory changes. Concurrently, Marathon Digital has expanded its heat recycling initiative in Finland, now providing heating to 80,000 homes using heat generated from Bitcoin mining. This project, which began as a pilot in June, demonstrates the potential for Bitcoin mining to contribute to renewable energy solutions, particularly in regions with clean energy grids. Marathon's initiative is significant, as it represents the largest application of heat recycling from Bitcoin mining to date, impacting approximately 1.4% of Finland's population.
