Regarding the previous data showing a capital outflow of $579 million from the GBTC Bitcoin ETF within two days of its listing, Bloomberg ETF analyst Eric Balchuna stated that the outflow data of GBTC may be due to accounting reasons. However, he can only use the latest data provided by Grayscale. Although he is unaware of the factors driving BTC price daily, if Bitcoin ETF wants to grow, it needs trading volume and low fees.
