$2.50 = 1 million gold cause $.25 per 100k is as low as it will go (literally hard capped), and boy do people have gold to sell
I recently blew most of my gold on high-end crafting mats (to protect against inflation), so I wasn't able to confirm this. But it appears to me that the hard cap is simply that you can't put up a gold auction for less than $1. So if you had between 4-500,000 on hand, the hard cap would be $1 for 4x100,000 gold = $.25 per 100k.
Can anyone confirm you can post gold with a price of $1 for 500,000 gold or more? Is there a limit to how much gold you can post for a dollar?
