On August 7, it was reported that investment bank Salomon Brothers announced the completion of inserting OP_Return notifications into Bitcoin wallets considered "abandoned," reminding holders to claim their assets as soon as possible. According to the company's official website, wallets that have remained unused for over 14 years may be deemed "legally abandoned," sparking discussions about potential means of asset acquisition. Some commentators have described the move as "clever but controversial." The company has already sent notifications to several well-known addresses, such as the "1Feex" wallet holding 80,000 BTC.
