Remember to NOT disenchant ALL of your quest rewards and drops. There is a new Blood of Sagaras in BfA called "Expulsion" and it is used in all primary tradeskills and it comes from using the Scrap-o-Matic 1000 to break down the piece (explation below). In alchemy you can learn to transmute it (Transmute: Expulsom, which generates 5 Expulsom per day from 10 Akunda's Bite, 10 Winter's Kiss, and 3 Anchor Weed). So some pieces may get more explusion from them that they give dust/shards.
Recently, Blizzard provided their own WoW Token system for players to buy and sell World of Warcraft Gold. However, the constantly fluctuating supply and demand means that prices will vary. Consequently, getting the best prices isn't guaranteed, nor do you know when you'll make a sale. You also can't trade or resell any tokens you buy, as they become instantly "Soulbound".
We’ll give different advice here, because the gems market is highly volatile. It can make more money than almost any other profession if you watch the market carefully and look for huge spikes in cost. Gems tend to flood the market during beginning to middle of a patch cycle, and spike in value around the end-middle when the content drought makes the market more scarce. It is advised in particular to watch the Tidal Amethyst gemstone, which is very economical to craft and has been known to spike at upwards of 8000%. With gems, it is less about rate per hour and more about how long you can hold before selling. Good luck!
Azeroth paid a terrible price to end the apocalyptic march of the Legion’s crusade—but even as the world’s wounds are tended, it is the shattered trust between the Alliance and Horde that may prove hardest to mend. As this age-old conflict reignites, gather your allies and champion your faction’s cause—for Azeroth’s future will be forged in the fires of war.
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.
