MASS (
https://massnet.org/en/) is based on the Proof of capacity (PoC) consensus algorithm that is decentralizing the mining industry. Anyone with storage space can mine this coin, there is no need of expensive miners and paying for electricity. A few days back it was said that it's just a useless coin like the rest of new Altcoins but very recently it's listed at
MXC exchange and as of this writing, its value is 0.69980$. Please have a look at the following resource and you will get to know that it's a good coin to keep in your portfolio.
If you see price chart of MASS its mostly around 0.10 to 0.60$ which in my point of view is not a bad value for a new coin. It has performed well since its launched on exchange. Still it has a long way to go, we have to see how this coin perform in next 2 to 3 years. If it maintains this price I am sure it can have big spikes.
