The U.S. Securities and Exchange Commission (SEC) has initiated an investigation into the classification of Ethereum's native token as a security, primarily due to the network's transition to a proof-of-stake model in 2022. This move has cast doubts on the approval prospects of an Ethereum ETF. The investigation has been highlighted as a significant event in the crypto community, with various sources reporting on the implications for Ethereum and the broader cryptocurrency market, including Blackrock's new fund on Ethereum. Additionally, discussions around Ethereum's classification have been stirred by comments from an attorney regarding a Swiss regulator's involvement and the Ethereum Foundation being investigated, although details remain undisclosed. The SEC's actions have also led to delays in the approval of a spot Ethereum ETF, reflecting the regulatory uncertainties surrounding Ethereum. Furthermore, Japan's decision to raise interest rates has been noted as a significant event in the financial landscape.
