Do you have a website?

I'm new here so take it for what it's worth, but my December batch S9 was as clean as a whistle and looked brand new. My January batch will be here tomorrow (go figure) so I'll report on that one. But I would offer up that the theory of Bitmain selling used units is pure conjecture. Just my observation and opinion

Same, although after thinking about the amperage of my PDU circuit I might have to sell one

But it's such a fun story to tell

A while back I picked up an S7 off Ebay. It appeared in really good condition so I put it straight to work without a thought. But every so often, about once a day, it would do like you describe. One board would stop hashing, no errors that I could see other than low temp. Since it was old and out of warranty I pulled the fan screws and then the other 4 screws that retain the end cap which in turn retains the hash boards. With that off and all cables disconnected (power and controller connectors), I slid each hash board out for inspection. I honestly wish I had taken a picture, but on one of the boards there was a giant moth partially against the heat sink and PCB. I don't know if he was grounding something out or just overheating one chip, but after his removal it's been working away for roughly 9 days now and no issues.

Long way of saying, probably best to remove the hash boards and inspect them for dirt, debris, or damage.

I apologize for the unsolicited PM, I found the correct thread. Thanks!

Definitely a big kudos to you guys for listening!

They just posted on Twitter, all sold out.

On edit: Tweet deleted... Damn should have screenshotted it.

Yeah, personally I would steer clear of a 3rd party pre-selling a pre-sale. Just wait for Bitmain or one of the other "vetted" companies listed here.

My January batch Bitmain order shipped early as well. I should have it in a few days, the PSUs got here last week

Rest would assume it get's tired Sorry couldn't resist. Like mentioned simply unplugging them is fine, the only reason I would power mine down would be for maintenance or cleaning. Otherwise you're losing money.

Just be sure to compare the data center overhead to what you might pay locally. I'd rather have my 50k close to me and make less profit than to have it 1/2 way around the world

So you really think you're going to stand up a facility and not have to do anything to *any* of the equipment for 6 months? Remember there's more to it than miners. There's everything from ac units, fans, network gear, PDUs, patch cables, the physical building itself, security, wiring, etc, etc.

 I'm sorry you're not being realistic, but I wish you the best of luck!

Right, but you have to figure this kind of stuff in to your business plan. So if you have a failed component or have to do simple maintenance how fast can you fix it and how expensive will it be to travel? Nothing ever fails in convenient schedules. I am just trying to say you have to monetize every single aspect, because it might simply be cheaper to mine where you are if you have to take travel in to account.

I'd still like to know how you plan on managing this remotely. Or (like I was asking earlier) are you going to relocate? I mean yes, the miners are fairly self sufficient, but what about the mundane things like changing air filters or swapping out a bad patch cable? What if you have to hard reset a miner?

Do you really believe a few people swapping to BCH to buy a miner affects the exchange rate? Come on, it was a new shiny alt coin, on the #1 noob exchange, cheaper than BTC, and pumped by Roger and company.

I'm not dumb, I know Bitmain is a big backer of BCH, but that theory is far from reality...

I'm curious which country you are in. I mean let's say you find a low elec rate and cool temperatures in Iceland. Are you going to move there? Or are you going to pay someone to maintain your hardware? Are you going to compare real estate prices?

I say all of that to illustrate that if you truly have $50,000.00 USD to invest you should look locally, not try to farm it all out long distance. What's your elec rate locally? What is the sq/ft rental price of industrial warehouse space? What are your internet connection costs?

I'll give an example. I want to expand my mining, I found a 20'x50' warehouse grade site for $5.00 sq/ft/yr with a 200 amp service panel. I will need to invest in HVAC (cooling and exhaust), internet connectivity, wiring, security, etc. I am located in the SW United States. So for me electricity is cheap, but I have to deal with very hot summers so cooling will cost quite a bit. The site is only 6 miles from my house, that way **I** can maintain it. Paying someone else's salary will eat away at your profits.

I have not provided you with a solution, but hopefully it gives you some things to think about.
