>It’s literally no different than the market manipulation you’d see on World of Warcraft or some other game where there’s a marketplace. People with a ton of money would buy up items at a lower price and then relist them at a ridiculous price - all the while having bots to watch for any listings that were significantly under theirs to make sure no one would buy except from them.
I don't get it how are they manipulating the market? Are they really cornering the market? If they haven't cornered the market, and are matching just below the price of competitors, isn't that the exact competitive behavior we want, driving down price?
Let's say an item's near true market value is something like 10 gold (not going to get into how that is determined but let's just go with it). It's going for 10g normally. You have 10,000g+. You decide to buy out the entire market from 0-25g. You can do this because the market for this item might not be gigantic and/or you have so much gold to afford this.
You relist the item for 30g. You setup a bot to buy anything listed under 30g before anyone has much of a chance to see it. The only listing people will see is yours at 30g and those above you. Since you cornered the market and are basically the only listing - everyone has to buy from you for 3x the usual price.
You do this long enough - you get a ton of gold out of it. Usually - the way the games try to correct this behavior so it doesn't happen all the time is through listing fees and other such things. It's to curb this kind of behavior - some even have listing fees that are directly tied to how much more you are selling this item over what you could get for selling it directly to an NPC. (To the point where it doesn't make sense to even list the item - only makes sense to sell it to an NPC)
It's extremely rampant in video games with any kind of market economy and thus why these mechanisms have to be put in place because otherwise it ruins the marketplace for many players. But - the great thing about our real world is that there are no controls for this! Thus, people can buy items for cheap, corner the market on that item, and make a killing. All the while - they take in real money from real people and give literally no fucking value to the system. They are purely rentiers.
