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.
The coin is NOT majorly broken but is still "getting back on track" and to say there are no valid blocks being mined and that all hash power is completely being wasted is absurd! Yes there are a high rate of orphans but that is due to the pos backlog and blocks are being found at 2-4 a minute and not the usual 1 a min...what was 75% orphan or waste is not the case now...orphans still high yes but valid blocks are giving about 60-75% of estimate payouts...so getting better...and it will improve more very soon...
