According to data compiled by Bloomberg analyst James Seyffart shows that the daily trading volume of US spot Bitcoin ETFs, including Grayscale GBTC, reached $3.2 billion, the second highest in history. The largest trading volume was on the day these products were launched, with a trading volume of $4.6 billion. The analyst emphasized that trading volume does not equal flow of funds, and data on fund flows will be seen later tonight and/or tomorrow.
