The Block reported that the average daily trading volume of the Zcash (ZEC) spot ETF operated by digital asset manager Grayscale reached approximately $1.7 million in April, more than double the figure from February. The Block explained, "While the recent trading volume of the ZEC spot ETF is still far below the volume recorded in the last two months of last year, it has shown a steady upward trend since January. Furthermore, as privacy blockchain use cases structurally increase, the proportion of shielded supply (ZEC volume with privacy mode applied) within the Zcash network has grown to about 30% of the circulating supply."
