Zcash current available supply is 767 ZEC! The supply will reach 100k during the slow mining phase before the full block reward will lead to a 7200zec supply increase per day.
At 20$ this would add 144.000$ value per day, so patience is the key, the 5-20$ range or below is where I start thinking about entering long zec.
I expect 2-4 years of constant down pressure with rally (pump and dumps) in between.

Overall ZEC looks like an interesting project BUT I am more curious about Mimblewimble which could turn out to be the zcash killer.
