The US Securities and Exchange Commission (SEC) has once again postponed its final decision on the New York Stock Exchange (NYSE) Arca's application for a carbon offset Bitcoin ETF. According to a document dated September 4th, the decision has been extended to November 21st. The ETF aims to provide a Bitcoin investment exposure in an environmentally friendly way by offsetting carbon emissions, tracking an investment portfolio composed of 80% Bitcoin and 20% carbon credit futures. Tidal Investments submitted the fund registration application in December 2023, while NYSE Arca submitted the initial application in March. Concerns have been raised about the environmental impact of Bitcoin mining, with the International Monetary Fund (IMF) reporting that cryptocurrency mining accounts for 1% of global greenhouse gas emissions. The delay in this decision also includes the postponement of approval for the Nasdaq One-Stop Cryptocurrency Investment Portfolio ETF.
