Market board logic - how to loose 100k in 8 hours

[Rasikko]

I wish the Market Board was like the Auction House in FFXI, all you can see is how much the last purchase cost, you guess from there and then you BID on that item. so it's like guessing how much you want to buy an item for. better than xiv mb

Wasnt undercut proof, but that market was a real beast.
