The Zcash nethash has increased crazy amounts in the last 7 days.... my 1 Z9 mini was making .6 coins beginning of the week and now returning .4 coins... There was a slow reduction since I got it in June, but the last 1.5 weeks, the decrease in returns have increased significantly.
Your z9 mini uses algorithm "Equihash" and a number of coins use that algorithm.
If you bought your z9 mini just to mine Zcash(ZEC) and hodl that single coin you are out of luck, I guess.
I, myself, use multiswitching(switching between different coins that all use Equihash algorithm) when mining and in my case have what I mine exchange to Bitcoin(BTC) and Litecoin(LTC) and then I choose to hodl BTC and LTC.
I use prohashing.com as miningpool with nanopool(ZEC into a wallet and autoexchange to BTC) and MPH(Multiswitch and autoexchange to BTC) as backup miningpools.
You can use whichever miningpools you choose.
You can also choose to mine to a wallet/exchange where you yourself can exchange to other coins/Fiat-money (£, $, ) you find attractive or best price.
All info about this can be found in this forum and on the Internet.
Good luck!
Not talking about coin value in my post. Was only talking about daily coin mined and the significant jump in hashrates causing less daily returns this week. Whether is ZEC, ZEN, ZCL or whatever Equihash coin is out there, this week, the amount of daily coin return has dropped by 20-30% from what I see. I was using Zcash as an example, the same can be seen across the other coins.
