Zcash will be next ETH, so if you buy it now, you can sale it later with good profit. Many people think that Zcash will be popular. May be it is privacy technology, which make it so popular already, before the launch. 
Gonna toss up a rig and split it with a buddy for the heck of it...6 gpu rig assuming you can use such yet...worse comes to worse it is an ethereum rig late to the party if z.cash tanks and we maybe get 1/2 our $$$ back kinda/sorta as a back up plan (and or have some nice gpu cards for sale or game servers)
boredom..is dangerous..but wth ....
