I have one advice for holders who mining and holding: sell this coin, or you will regret for your choice when Zcash will fall to 15 dollars.
Why are you looking at it on a per coin basis, instead of market cap? ZCash is valued at way below XMR on a marketcap basis. So saying it will become in line with XMR after a dump is meaningless.
The supply of ZCash is just 746,394 ZEC
