Hey nostr:npub1d3f4m9dgvkdjxn26pqzsxn6lpfn78sxwllxyt8mp76q0a9zyyjlswhr4xv, how do you factor daily trade volume for precious metals. Is that based on future contracts AND ETFs or just future contracts?

If 700 million ounces of #silver is mined/yearly. And #platinum is only 6 million ounces/yearly. How can I factor how many ounces of platinum is traded daily?
