The SEC has issued a warning about the risks associated with Bitcoin (BTC) and Ethereum (ETH) ETFs, labeling these cryptocurrencies as highly speculative investments. This summer, trading began on ETPs tied to the price of Ether, raising concerns for retail investors and the broader financial system. Glassnode reports that Bitcoin ETFs have a significant influence on the market, affecting up to 17% of spot volume, while Ethereum ETFs impact only 1.7%, with an influence of ±8% and ±1% respectively. Additionally, the FBI has warned that North Korean hackers are targeting Bitcoin ETFs, posing a potential threat to billions held by custodians.
