It is if you watch it and switch pools around. I dont use it anymore but when i did back in FEB 16 i turned 200$ worth of bitcoin mined neoscoin and sold said neos [unfortunately]with 1600 for a lottle over a bitcoin for an almost 300$ profit, sonetines i would send high hash for like a minute to a peercoin pool to get the most shares till it got solved but make sure i had the highest, pissed off alot of consistent miners there lol
