You didn't actually say anything about your link, and I'm not clicking a GitHub link, but there happens to be a preview in my app that says "asset prices by vitorpamplona" (makes me wonder if primal used my device's internet connection to load that from GitHub)
When you say "asset prices" as the title of the nip it sounds like you want a simple database format for tracking real-time updates in a data value, but with the spec saying it should only be used for asset prices?
NIPs that would make sense for this topic would cover a commodity market where you can submit bids and asks for an asset, or a simple database format for tracking real-time updates in any data value in general
Not worth clicking a GitHub link to find out if I'm missing anything on this one tho
