Make sure that you use ‘track minerals’ on your min map and try to keep mining until you fill up the last stack of ore, at that time, you can sell it easier on the auction house. It’s a lot easier to sell a stack of 20 ore than it is to sell 18 or 12. I also recommend that you smelt some ore and sell the bars. This will make it easier and faster to sell everything you find while mining.
That's where i'm at now. I got into it late. I had 40k to start. Sold fish up to about 100k total starting capital. Started making and selling decks when they were going for 80-200k on my server. Morons have repeatedly undercut decks by 30-60k at a time even after the market has been reset (not by me) multiple times. Now the decks are 25-80k... I did manage to make 3.5m gross in the last 2 weeks. Now the individual cards are selling for MUCH less than the decks so I may stop crafting myself and just start buying the individuals... idk where to go from there though. Do you think the decks will hold any value moving forward? I'm kind of hoping for something similar to obliterum in legion to increase the ilvl and keep them relevant.
