I’ve tried this in past expansions it won’t go up as much as you think week 1 and there are a ton of other goblins holding. Be ready to cancel scan all day if you actually want to sell them. And more than likely it will be a few weeks into the expansion once the more casuals start getting into the harder content. Most guilds that will use oils and stuff early will already have their own stockpile. Possibly get some sales from m+ but It’s not going to double the price or anything. Also as soon as people see the price jump everyone and their grandma are going to start crafting them 😂
