I'm pretty sure we established this isn't a scam, but a buggy pool on top of a buggy coin.
There is a fairly active member about 10 pages back that was mining pretty heavily, he got about 1/2 of his payouts last I heard (Don't remember his name, but his logo is a cat lol)
The other half of his payments were sent, but not received, apparently due to a bug in zcash?
The OP has said he is regularly having to move the pool back and forth between a backup wallet, because zcash keeps crashing/corrupting.
As far as I can tell it is a one man shop, so once he goes to sleep, the pool will most likely go down until he gets up again.
Suprnova doesn't appear to be much/any better.
I think Nicehash is working, but I don't like them, hopefully OP can get everything working soon.
