It was profitable to mine raven a couple months ago till the btc drop and rvn itself dropped pretty hard still,  i have found is zero coin is good mining right now i run 10 x1080ti's on suprnova and mine a little over 25$ a day depending on my overclock,  luxcore is also good mining with the algo update but at this point in time zero is the most profitable coin to mine with reasonable stability in price  there are other coins that are more profitable but there isnt enough buying volume at the profitable levels
