Also OneMarket should be viewed as a tool to increase the Cloak currency velocity and to provide a way to spend the currency thus increasing demand and consecutively increasing price of the cloak currency. The real thing that matters is the anon feature. Darknet users will migrate to cloak only if it is the best at providing anonymity. So PosA is the feature that needs to be closed source at least for a while, but the market does not need to be closed source.

There is also the possibility that other decentralized markets will be developed that will allow the use of multiple currencies. If this will be the case then, again, the coin that will win will be the one that has the most secure anonymity feature.
