I am mining MONERO from miningpoolshub.com.
NsGpuCNMiner.exe -xpool stratum+ssl://us-east.cryptonight-hub.miningpoolhub.com:12024 -xwal xxxx.yyy -xpsw x -dmem 1 -h 1900 -mport 0
you aren't mining monero, you use the port 12xxx, you mine cryptonight algo, sometime monero sometime another coin.
and with 12xxx it's for multi algo, so sometime you mine nothing.
