first Since its launch it seems to have a steady price between $0.5 to $0.7. I think so far the coin will work well on every exchange. but in my opinion, for now we are better off buying them from every exchange when compared to mining them. I think this is more interesting
MASS has gone to its ATH of 1.6$ since its launch. The price was stable in between 0.5 to 0.7$ but now it has gone down to 0.04 - 0.05$ and is stable in that window. I do agree with your idea that its better to buy this coin from exchange rather then mining it. I don't think there is any loss in buying MASS at current price.
