Justin Drake, a member of the Ethereum Foundation, responded to questions about the Ethereum Foundation (EF)'s financial reserves in an AMA. He said that the EF's financial report will be released soon. Currently, EF's annual expenditure is about $100 million, and the Foundation's main Ethereum wallet holds about $650 million in ETH reserves. In addition, EF has enough fiat currency reserves to support operations for several years. He mentioned that the sale of ETH was temporarily suspended for regulatory reasons and was only resumed recently. Roughly estimated, the Foundation's financial reserves are sufficient to last about 10 years, but this period will vary with the fluctuations in the price of Ethereum.
