Grayscale Investments’ spot Bitcoin ETF had a first-day trading volume of $2.3 billion on the New York Stock Exchange after it was approved, but the company’s chief financial officer Ed McGee said in an interview with the Wall Street Journal that it must pay more attention to risk management In communicating with participants, he pointed out that Grayscale GBTC is currently an open-end fund, and the number of Bitcoins that Grayscale is exposed to as a fund manager will also increase, which will affect Grayscale’s Bitcoin on a more variable basis. For currency-denominated fees, Grayscale is currently accepting a new risk management model, and the fund’s risk management is currently in a fairly stable state. Now, as more Bitcoin may enter or leave the fund, it adds a new variable for Grayscale to manage volatile assets. (WSJ)
