Any way I can get any information from you guys about the A7 chip? Or even the A6 chip? Not a single one of my inquiries about anything have been responded to since last June so I gave up after about six months of trying.

I had set up a big sale of Avalon4 units between Canaan-Creative and a guy I was consulting for who was starting a farm. He ended up never paying for the order (a problem the guy had often, which is why I use the past tense in regard to my dealing with him; I was tired of facilitating his laziness screwing people) so I assume I've been officially spurned on my deadbeat client's behalf but I'd really like that to change.

Sense miner design and production become a very difficult (mainly about cost, timing, supply chain, manufacture, software, etc...)job, I hardly believe any 3rd party can do a competitive design. I think anyone (who is not in present industry )should give up for self-miner-production-for-self-mining . Or you have different opinion?

If you sold him a7 chips with documentation he could build good gear.

One problem with the a6 vs the a4.1 was it was locked via software.

That works for many farms but for some of us an unlocked miner has more value.
The problem with just about all chip builders is they rather gear to bigger farms.

I did a lot of work to help sell a6s to the guy with limits to cheap power.

I am in a joint venture on a larger but not huge solar array.

The power is cheap actually cheaper then most can do.
If we mine 8-11kwatts year round the net power cost would be under 2 cents.

But that is all the power we have on the 2.5 acre spot.
So an a7 with the downclock under lot option is better for us.

We could just buy a few more and down clock while the starting cost would be higher for us in the long run the better efficiency allows for more hash power.

10 at 10 th using 10 kwatts is 100 th
12 at 9 th using 10 kwatt is 108 th
Both bitmaintech and Avalon did not offer easy under clock down volt the last round.

I know side hack could build a more efficient miner with quality chips.

A lot of people are anti Asian when it comes to asics.

I personally do not care where gear is made or where chips are made.
But I do care that you won't sell chips to people that want them.
By you I mean every ASIC builder simply won't part with chips.

I understand you want to make money , but having your chips in other peoples designs would make you money not cost you money.

I also understand you can't tell us all the why of your selling tactics. There are restrictions. Set by your company I don't think help your company long term.

Just remember at least 75 percent of all ASIC gear is in China.
Not safe to have all your eggs in one basket.
Suppose USA elects Donald Trump and he decides to default on the debt.
We all know,he has done this time and time again.
With his businesses.

Since USA owes more to,China then any country it would rock your world.
It would be nice to know more of your gear was in another spot then China.
In case there is a lot turmoil due to the default.

Also multiple plants with chips and build gear protects you from earthquakes floods etc.
