So I have an S9 that has a dead board so I’ve been running it at a steady 10TH for over a month now. I am using a mining pool. I see that it shows 1 block found… if this the pool or did I find a freakin block?? I beg you tell me that this was the pool I was in.

~50k per month in electricity (400,000kWh / month)

Can’t wait to post the final setup

Running S21 XP 270Th/s units at $0.07/kWh can generate $119K worth of Bitcoin for just $45K in power costs.

I just got back from a trip to Xinjiang (western China) where I was visiting a friend who lives in a pretty rural area.

While I was there, a few guys came over to install what he called an “electric boiler” for winter heating. I asked him how much it costs to run through the winter, and he said, “Nothing.” I thought he was messing with me—like, you still have to pay for electricity, right? But he told me the company gives you the boiler for free and covers the entire electricity bill.

I didn’t really buy it at first, but he said he used the same setup last winter and literally didn’t pay a cent. He also pointed out that the boiler was way bigger than normal and needed a SIM card for 4G data, which immediately set off alarm bells for me.

With his permission, I opened it up.

Inside were four Antminer units. The whole thing uses water cooling, and the hot water gets circulated through the house for heating while cooling the miners at the same time. Honestly… brilliant. The “heating company” is actually a crypto mining operation. They registered as a heating-solution provider so they can access extremely cheap electricity in the region (around $0.003/kWh).

Here’s the interesting part: local governments don’t really allow large, centralized mining farms anymore because they suck up a ton of power and can cause outages, which messes with residents’ electricity use and local factory production. So these guys sidestep that completely by disguising their miners as home heating systems. They get cheap power without raising red flags, and residents get free heating. Total win-win—and kind of genius, to be honest.

I hooked my laptop into the local network the miners were on. The system they use is called “Super SAIYAN,” and the pool address was: http://a1.tookmi.com:2411

We talked to a bunch of people in the area and estimated this company has around 10,000 S19 XP Hydro 251T units running like this.

With winter lasting about six months there, I’m really curious: with that many units mining nonstop, how much revenue would they even be pulling in?

Happened about 2 hours ago. Wow.

I now have 6 workers running. Anyone know where I could get some kind of stand maybe ?

These have been running for several months. It’s pool mining on Braiins, I have 2 other Nerd miners overclocked, at only 19th. I thought if it’s in a pool everyone would get the block round but it’s only on 1.
