it's still profitable to buy Z9 or A9 ?
i have almost free electricity (0.02-0.03$ per kwh)
is it possible to achieve Payback under 4 month?
any advice?

Returns have halved every ~2-3 weeks. equihash is quickly heading towards "don't mine it", in my opinion.

Z9s still haven't shipped also.

I do not think that they halved every 2-3 weeks. I started mining on one Z9 mini around June 27 and was getting ~ 0.15 ZEC/day. Now, I am getting ~0.085 ZEC/day (I am only running at 675 MHz). In other words, it did not even halved for me yet (after 2.5 months).

Look at the difficulty chart

https://www.coinwarz.com/difficulty-charts/zcash-difficulty-chart

I do not see any of the dramatic drops, you are talking about. You understand that we earn less in $ because Crypto dropped a lot. What are you mining now with your GPUs? Perhaps not ETH (LOL)

I should clarify -- some of the loss is indeed in the conversion to USDT -- my accounting is done that way daily due to (annoying) US IRS regulations.

In pure ZEC, I've gone from an average of 1.6-1.9 ZEC/day (7/17/2018) to an estimate of 0.9 today (09/8/2018).
So yeah, not halving every 2-3 weeks, but a marked drop and a continuing downward slope.

I have 12 Z9 minis running currently (~192-194kSol/s pool side) and have 3 Z9s on the way (in theory, if bitmain every ships). I don't regret the 12 Z9 minis, but I'm unsure on the Z9 large units.

You referenced the difficulty chart, which as of this moment shows a 28% 1 day difficulty change, and a 58% 30 day difficulty change. While I realize there is a lot of fluctuation in the rates in a given moment, model out 60% month over month and see how fast your returns disappear. Bitmain is going to keep shipping these until people quit buying them and I expect that the units in flight over the next 30 days will at least add another 60% difficulty...

Just wondering what makes you think difficulty level will spike 60% per month going forward when historically it's only been going up by 20% per month and most recently less than 30% per month as per CoinWarz ZEC difficulty chart: https://www.coinwarz.com/difficulty-charts/zcash-difficulty-chart

Considering both the Z9 Mini and the A9 Zmaster have been out for months, do you really think the addition of the Z9 will crank the velocity of difficulty level growth to twice what it is currently ie 30%pm -> 60%pm?

I'm looking into purchasing the Innosilicon A9 Zmaster since they have recently lowered its pricing in response to the release of Bitmain's Z9 but I'm a bit concerned the difficulty level might blow up uncontrollably once the Z9 floods the market. I have access to pretty cheap electricity (5-6c USD/kwh) but still, at 60% difficulty increase the ROI will quickly turn to shit!

Any advice/tips would be most appreciated!

I can't predict the future, just at the moment I looked at the chart when i posted that, the 30 day calculation was +60%. I did say it varied.
Z9s haven't hit and the impact of the last round of minis has definitely been felt.

make your own decisions re: mining

You can adjust miningspeed on this link day by day and se if this helps understand miningspeed vs mined ZEC.

https://www.cryptocompare.com/mining/calculator/zec?HashingPower=193785&HashingUnit=H%2Fs&PowerConsumption=2500&CostPerkWh=0.11&MiningPoolFee=1

I have set hashingpower to equal right about one(1) Zcash per day/week/month/year per today.

If difficulty increases you will have to increase hashingpower or you can look at Mined per day/week/month/year decrease and calculate what percentage profit decreases per day/week/... at given hashinhpower. Then just calculate your your hashingpower in percent of 193785 H/s and calculate your own or whatever you want to calculate.

Don't forget that mining should not be done to 'get rich quick'. I think you need to mine/buy/trade and Hoodl "cryptos" and this should be done longterm.

One should not "place all eggs in one basket". If you don't go for "Gold" like Bitcoin. Will probably be like Gold backing all other succesfull cryptos. (My personal guess.) But will only be safe like gold. Will probably go to the moon in Fiat money value but we will not understand Bitcoins true value until we get Bitcoin in Trayounce of gold/silver/...

When Bitcoin or cryptos at large goes to the moon in Fiat money value that can also happen because Fiat money looses it's value because hyperinflation and/or Fiat money debt is transfered into cryptos.

I guess that in the future using Bitcoin will be like moving Gold to settle big deals.
I can absolutley be wrong and if something happens in the future that gives me good reason to reconsider my belives I will surly do soo.

I would recommend listening too Bitcoin Ben, Roadtoroota, Greg Hunter, maneco64, Reluctant Preppers, x22report, x22report spotlight, SGTreport, The Money GPS, Dustin Nemos2, prayingmedic, Seething Frog, Amazing Polly, Stefan Molyneux, Jordan Petersen, Michael Trimm, ITM Trading, Saledaddy1, Simon Harris, Rebel Media, jsnip4, AMTV, Sarah Westall, Clig High, corbettreport, Judicial Watch, RonPaulLibertyReport, Project Camelot, Dr. Steve Turley, Erin T Scott, Bill Whittle, The Rubin Report, ... on youtube.
