Last night, the site recorded $3 billion in Ether transaction volume in August alone, and set a new daily record of approximately $323 million. In terms of volume, online marketplace eBay generated $22.1 billion in gross merchandise volume. Although this is significantly higher than OpenSea's August totals. All of these figures, of course, pale in comparison of Amazon. Amazon recently eclipsed Walmart for the title, and the company posted net sales of $113 billion last year.
