ok, i'll bite, .....without being a wiseguy, explain in detail, how to make these millions.
I play a hell of alot longer than 15 mins a week, and seriously want to know.
Ok i'll explain a couple of methods.
The one I mentioned above. If you like to travel just runa around all the lands with homes and venders away from luna. Many of them item prices are very cheap for demand items. Buy them out rent a luna vender place a little lower than what they going for in luna but not that much lower just low enough that you can make a profit. Example finding 10 ecrus for 100k in the outside lands then bringing it to luna and selling the 10 at going price maybe
350-450k depending on shard. Hell even if you find them at at 20k below luna price and sell it at 10k below luna thats 10k profit for nothing. You do this for any item you see that is in demand enough to sell. You have become a beggining reseller.
The key to this method. Know what it's in demand,Know the current average market price,and 30 mins or more of running around locating shops like this marking them for easy access later. Make money while you sleep. Good return for minimun amount of time.
Another method.Becoming a supplier. Mine your own,grow your own,,chop your own,Make your own,. These are time consuming you make the most back on these things but it does take time. You sell this at retail rate but you can sell them much faster by just supplying other resellers.
Another one. Have a develope character head to stygian abyss collect essences and sell them really easy. Less time consuming than above but more fun and the returns are good.
PvP- champ spawns and scrolls really the only real gold market for pvp area.
Make large return but very time consuming and alot of luck of draw.
Selling pets. Frustrating to get right pet then train then find buyer so it's just not enough gold for amount of time people put in.
Filling Bod's for rewards. Time put in is beyond resonable but gold is steady and profitable. Good to fall back on.
Above all people will need to learn your vender and be confortable of what you sell. Once you have steady customers your good to go. Keep it stock people are fickle one day they come and see a empty vender then they won't come for a week again.
Multiple other methods like armor making,imbuiing,providing that exact product needed in the right spot, Guild merchanding,auctions,events,selling of bulk items,Home trading,cross trading,event selling,Fad selling, vender renting, rare selling etc..
Just have to put in a little time. Hell just going to trog cave and bashing on those trogs for a hour a day can net you 50k-200k hour from gold and the items can be turned into imbuing resources and any rare drops a bonus if people really wanted to go that route but compared to the other methods above this is just too slow rather just farm essence to sell on the venders.
