If you follow the order book on Masterxchange, you will see a few large sell walls that come and go. Most of them are in the 500,000 - 1 million MAID range. Every time the sell walls get bought out, they get reset higher in similar amounts. This leads me to believe that the same person is buying up his own sell walls to create artificial volume.
While these markets are completely unregulated, I am suggesting that large holders either pull their sell orders from the market or reset them at a higher price. Having such large sell orders on a low volume market artificially represses prices.
I believe that prices should reflect status of development, not the price that one or more whales decide to set.
