switching from pow to pos makes much more sense and would be better for the coin/price as a whole.
pow is pretty much useless for underdogs like this as there is little incentives to mine it in the first place since the coins mined doesn't even cover electricity.
pos on the other hand, people would have an incentive to hold and utilize the coin instead of merely as a trading vehicle.
I looked at the CS shop as well, and it's practically empty. I doubt there's much volume in that either.

as many coin as there are in circulation, it would be far more beneficial for both the current holders and potential new investors.
to be able to lock away a large portion away while it pays out interests and support the network at the same time.
right now if you want to trade the coins on cryptopia, the bid is 2sat, sell is 3sat. a huge 50% spread.

pandacoin (a pos coin) for example has far more coins out there, not anymore development than photon, yet the marketcap is far greater.
because people are not hurry to sell them.

pow is really getting obsolete these days for all but a few dozen coins.
