Here's my 2 pecs:
The biggest seller is buying single CLDs in auc for higher than he's selling them. And if you have enough peds, and I believe he has, you can manipulate a market the way you want... especially a market this size.
The prices have been going up for the last few weeks big time. And the ROI just keeps dropping

Now we have our own little stock market inside eu, yeii...

Everybody, go crazy
Oh yeah, this was a price check...
As I said, it's like stock market now, the price is what people are willing to pay, even tho it's just one guy who's setting the price tag...
