What's the block reward for PoW now ?
Mining on 13 RX580 8GBs only yield about 22 Loki a day. Before the Service node changes I was getting 35-40. Tough coin to mine here, might be better off switching to a diff Cryptonight Heavy coin.
It's normal rule. More masternodes/ service nodes in the network, less rewards for miners/ stakers.
It's happen all the time to all coins which have masternodes/ service nodes/ secure nodes on networks, so LOKI is not only exception.
