MASSNET main strengths are its PoC consensus algo and ability to mine it on any device. With time we see its complexity going high because of its popularity there are too many people joining in the mining process. But still its fun to mine the coin.
It may be fun but its definatly not much worthy to mine MASS now. See its price now, I am very much sure that you wont get much profit by mining this coin. So better go to exchange and buy this coin , its standing on 0.30$ for very long time. Chances are that it will go up from here.
