Discovered this forum yesterday, so Hi !
I am at about 34k myself, 3 level 80 toons with epic flyers/northred flying and a travelers mamoth, and dual spec for 5 toons.
I guess I am just "barely rich" by the standards of this forum, but for my guildies I am drowning in gold
In vanilla wow I was at about 3k, in BC about 15k, I always bought my riding skills as soon as available, never knew the pain of slow flying.
In vanilla I made my fortune by buying low cost darkmoon cards and aces, and selling the resulting decks for a nice profit. At level I was buying all the iron I could to make iron grenades and make a profit just by selling them to the NPC
In BC it was mostly farming primal air as with the mote extractor when they where in high demand.
In LK, I do not know, gold comes by naturaly
I'am making quite some gold selling spellthread of low cost materials and since a few days I have maxxed alch, JC and enchant to make some big profits
