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-chartConsidering 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.
