I think until now, there was literally no benefit in pumping the coin because people could always buy massive amounts from Ohad without impacting the market price. At least that is what provided an incentive for me to keep my mouth shut. This changed since Ohad is sold out for now and doesn't set any price in the near future.

It would have been more beneficial to spread the word only after July 1st. when Ohad would have raised his selling price 10-fold. Then people would not have bought from Ohad but from the market until the market got into equilibrium in relation to Ohad's new price. As it is now, a lot of people got their hands on very cheap coins from Ohad which they should not have gotten and did not deserve to get in the first place. This is the only market manipulation that I can see. The price will rise again after those people got rid of their coins, for cheap.
