Currently Nicehash.com pays a lot for x11 mining, that's the way I increase my DMD stack at the moment
ETH mining draw hashrate away of other GPU algos make them more profitable
but u can now mine ETH too using nicehash and earn DMD payouts via https://multipool.bit.diamonds/
but ETH mining is more AMD friendly and i run NVIDIA cards
mining ETH also make my system lagging to much for daily use other algos have way less impact
on a system thats not only used for mining
