It totally depends at which point you are entering the mining. When MASS was not listed on exchange and has not established any price its complexity was low aka you get more MASS tokens for less storage and vice versa. Right now its better to buy MASS from exchange rather then mining it.
If you can get MASS token for 0.04$ then why setting up a mining rig for this coin? wise people do wise moves and its better these days to buy this directly from exchnages for log run rather then mining it. Rest choice is yours.
