So plat just basically accumulates over time. Everyone just stockpiles it with no dump (until Velious tradeskill stuff or Luclin horses and gambling). SOME have gotten wise and started tradeskilling for shawl and rings which dumps some cash. The reason the prods matter is because for the most part they were controlled by 2-3 people so their prices never dropped. So there was always a demand for 3kr for a prod. So people selling plat would just keep upping the prices and people desperate for HS keys would pay it. AND, if they were next level, the prod farmers themselves would be peddling kronos they earned for plat, waiting 3 days, and upselling it to make plat on top of plat. Now that kr is currently used for high-high end items and monthly accounts, the prices have dropped because the demand has dropped. There's no MUST-HAVE item. So Krono has steadied at 8500 for the last 5ish days.
