Is that sea sand? Why would it needed to mine ?

No, the sand is no beach sand and Inner Mongolia is a landlocked province. What you see is an example of desertification caused by over-farming and dry weather. The place is very dry and windy. The buildings where the machines are housed are not completely enclosed.

The top of the walls are open where they meet the roof correct? Good for ventilation, bad for keeping out dirt I guess.

Great photos!  I am an engineer and on the job site we must wear steel toe boots, eye protection, and hard hats.  Tell the men there's nothing cowardly about protecting yourself.  Think of the armor ancient Chinese warriors wore to battle.

Love the photo with the gps track, quite a mountain road!

What is the one that looks to be some sort of border crossing, what do all the signs say?

Yep, we were crossing the provincial border between Shaanxi and Sichuan. The signs are Chinese characters for Sichuan.

As you are near mountains and it is cold, do you have any problem with heat?
No, we haven't had any problem with heat so far.

That looks incredible.  I am particularly happy to hear that you are true believers and trying to hold your mining earnings.
Sorry if this has been asked before, but do you know if you are the biggest farm in China, or are you part of a mining network there?

Do you solo mine, and what is your up-time like?  Are there any disadvantages to being located in China for bitcoin mining?

We are one of the largest. Huobi, JUA and Bitmain are pretty large too, I am not sure which one is the largest.
We mine with multiple pools.
The disadvantage of mining in China? Can't think of any right now, maybe the business culture here is quite different from in the West?

I was thinking what is the use of sand, but it's ok, good luck.

All of that sand could not possibly be good for the miners at all.

Given the short economic (not functional) lifespan of some mining hardware, it might not matter a lot. I expect that fans wear out quickly as a result, and miners themselves might increase in temp. Vacuum the miner, replace the fans, and it's as good as it was when manufactured, though no more efficient.

Cheap used miners + Cheap Electricity == Profit (unclear on how long)

I think Eric has stated that this is their business model (more or less).

are all those employer paid with bitcoin? and how much, their payments is a part of roi on new equipments i presume

or they work for free because they belongs to those who own the miners?

Sarcasm intended?
No, nobody on these photos are paid in BTC, except the photographer, which is yours truly. Most of them are villagers / temporary laborers we were lucky to find in Dalad Banner, Inner Mongolia. We hired them for RMB 150+ RMB 10 lunch subsidy per day.
They don't belong to nobody but themselves. They trade their labor for money just like everyone else who are gainfully employed.

actually i was serious about them payed in btc, and i cannot see the joke to be honest, btc will be one day one form of payment for every kind of work, i can't see how you may find it, like a joke sincerely...

For 99% of the population in the world, paying them in Bitcoin would be only slightly more useful than paying them in "Farmville Dollars" or some other fictitious currency. With no disrespect for their workers, I'd be stunned if any of them had a wallet to send it to even.

Eric: In your travels their, have you noticed any shops that would accept Bitcoin as a form of payment?

It was still pretty large when I was there - from June 15 to June 16, but a lot of shelves were empty and that didn't include the those emptied by us - we just moved 6,000+ Avalon 3 back to Kangding. So I personally think the operator of the farm hadn't been 100% honest with their users for I never saw that they openly stated that it had rented hash power to a few large miners. HaoBTC only accepts deposits, we don't do hosting. Have to say that this is a space where transparency and honesty are still in short supply. Sigh.

Thank you for having the time to reply. I see those guys from that farm will have some issues in the long run...

Best of luck for you all Smiley

The only China-based BTC-accepting retail businesses are online so far. Even in large cities like Beijing where i lived, there are no more than a couple coffee shops.

One caveat of relying on hydropower is that in winter, the supply is likely to be limited. This is something that I only recently learned. Sorry if this bit of information came a bit too late.

June 20

Around eight last evening, all of a sudden, the dynamos nextdoor became much louder than usual.
"Oh no, Internet outage again!"
Someone shouted.
The second time in a month.
"Can be a rock. Can be the villagers just because they feel that they own the place." A colleague said in despair.
We had a dedicated light fiber cable provided by China Unicom. Though every time it broke the Unicom workers responded fast and the miners were back online within hours, we decided that we better get a backup connection.
China Mobile agreed to give us a cable but we waited for a month and nobody showed up.
Mr. Zhu, the head of the hydropower station decided to pay a visit to the China Mobile office in Kangding so I got a chance to visit the famed city.
The city of Kangding is perhaps most reputed for a love song https://en.wikipedia.org/wiki/Kangding_Qingge that bears its name. It is also a popular destination for backpackers and bicycle travelers.
After two hours' trip, we arrived.
It is a beautiful city built amongst the mountains, no words can do its beauty justice so I will let the photos do the speaking!
Apologies for my amateurish photography.

One hour of bumpy road like this, as always

Then a city emerges like a miracle

The Tibetan ornamental motif is unmistakable



Mr. Zhu is the man on the right.



A PLA base - I never seen barbed wire used this way in other cities.

Locals dressed in their traditional costume

A Tibetan Buddhist monk wearing a crimson "skirt"

Statement:
1. Due to popular demand, I decided to produce a series of short vid to show activities inside our BTC mine. Here is the first one filmed this morning.
Link: https://youtu.be/jtp4gNeGTSw

2. Due to increasing amount of user inquiries, I decided to build a support group for international users - If you haven't heard of WeCaht, it is the go-to messaging app in China. I am not on this forum 24 hours a day, so if you have something urgent, please download WeChat app, scan the QR code and post your questions there. I will reply ASAP.
