Yes PoS moves the network as well. Give it a whirl blocks moving along fine.
Bottlecaps is a MAJOR BROKEN coin right now. Thankfully we aren't seeing forks, but there are ZERO mined blocks being found. You should tell all miners to stop mining, as they are wasting the power used, because they will not be paid for the work done, and they aren't helping in securing the network. With v1.5, you now have a coin that is 100% being powered by PoS, no need for miners anymore.
