The hype of ZEC had gone, Just remaining a little whale waste his money to pump it sometimes. Interesting for watch it.

wait a year after ZEC was running and we can make any conclusion about that.
There is a lot of potential in the zero knowledge proof.
Depends on how we can be digging it.
It is best to buy ZEC instead of mining it, in my opinion, as mining it with founder's reward would be less profitable per hashrate.
Nevertheless, let's see how everything goes for all Zero Knowledge Proof cryptocurrencies, in this new year of 2017.

Less or not was depending on the mining difficulty. It will get another decrease as quickly as possible.
At least in this year the miner will continue his dumping phase. But you may think for buy some of the ZEC below 0.045.
