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
Mining has its own fun and once you start doing it you do it for your own satisfaction apart from earning profits. But yes its better to buy in terms of profit ration since in mining you have to invest lots of efforts while on exchange price of MASS is very much in range these days.
