ZCash isn't quite as well off, but it'll still probably take months for the Z9 and competition to drop profitability by half even though the efficiency of the new ASICs is a ton better than existing GPUs.

I know you're a veteran here and i've actually followed your posts in the bitcoin mining section but really? How can you seriously say that it will take the Z9 and similar ASICs to drop profitability when we already see that GPU mining equihash has already tanked, TODAY.

You may argue that $0.1 is still profit but seriously, the Z9 ASICs are still arriving and a huge spike in difficulty is still incoming. Not to mention this new beast by A9 zmaster which does 5 times the hashrate of the Z9. Are you mining with free electricity? In what world will equihash still be profitable?

Why don't you assess the factual parts of what he said?

"Months before profitability halves"

That's fairly accurate based on what I've calculated. Of course it doesn't factor in the entire market dropping 10%, etc, which is probably what you're referring to in today's 'tanking'.

Total Nethash of all Equihash mineable coins; 700mh
This was actually 750mh 3 weeks ago, or about 1,500,000 1070ti equivalent.

Ask yourself how many ASIC need to be pumped out to halve profits?
700,000,000 sols worth - 14,000 A9 Zmaster or 70,000 Z9 mini.

Ask yourself how quickly that will ship? and pay attention to the dialogue coming from Bitmain / Innosilicon. Read between the lines.
Both are doing small Batch 1 with much larger quantities "in a couple of months"

Now honestly assess the profitability for GPU mining Equihash, ignoring market movements.

low% chance that profits are halved prior to August 1st.
high% chance that profits are halved during August
Almost certain that profits are halved by September 1st.

Now I ask you again, look at the facts of what he has said and then look at what you have written.

PS: in case you skimmed the Innosilicon announcement:

A9 ZMaster is in stock and ready to ship right away based on payment order with limited quantity. The sales price is $9999 shipping from Hong Kong starting June 10th based on payment sequence. The 1st 300 batch one customers will receive free shipping and free PSU. Hosting service is optional. Batch one shipment will end on June 25th as long as stock lasts. Batch two shipment starts on August 15th with ASICs offering.

A9 Zmaster is the most profitable miner today. Be sure to be the 1st to own. We believe Batch One customers will enjoy great mining experience with little competition for a few months, as it will take a few months for anyone to be able to produce another decent batch after this limited shipment anyway.

They are literally telling you what QuintLeo has said.

I have R9 390 mining with $0.16/kWh. For the rig, the revenue is $5.1, electricity is $3.84. The profit is $1.26 per rig. So it just needs the difficulty to rise 25% to make it no profitable.
