Haven’t bought an asic for a couple years and I am super weary of scams
I picked up a few before from bitmain
Quality wasn’t the best in the s17 64th units the 50th pros slightly better
What is the current line up like quality vise s19j 100- s19 pro 110
Any line to avoid? Is there a new miner around the corner (with the chip shortage )
I am from Canada so it’s impossible to find a local place that is trustworthy been working kijiji for a month but I don’t wanna buy something new at inflated prices and no warranty ? As bitmain only warranties the original purchaser per their website, is this correct ?
Bitmain has spot order right now at 10500usd for the s19j 100th is this reasonable
Usually get hit with 13% tax and about 300usd for shipping
I contacted eastcoastmining and it’s 1000 usd more for the exact same thing ? Is there any benefit going thru them or are there other options right now ?
I purchased from bitmain before are they going under? Still reliable ?(only asking due to current Chinese laws on mining)
Any input from the good community would be appreciated
Hi! It's still available on official Bitmain site: Antminer S19j Pro 104TH/s Spot Order Hashrate: 104TH/s Weight: 17kg Shipping in 5 working days after fully paid $11440.00 They will have a bigger price after few month because of low W per TH, so it's the best choice. Due to the rise in the price of bitcoin, even the old ASICs are quite profitable, but if it drops to at least $ 48,000, most of the old ASICs will work at 0 or at a loss, so people will look for more profitable options, but at the moment it is s19j. I also saw the news today that Ipollo is launching 2 new miners, but I saw them on the Internet, but in reality, never. |

No, I’m not a hosting company but I have a land and want to build it, but it’s not in US. I just doing some research to understand is it interested for people or not. (If it will be a big farm, I can receive really low price electricity, lower than 0.04$, if not, 0.055-0.075$. It’s in Ukraine. Now I live in Ireland and have near me company which have 1+MW green electricity, but here price for electricity is so big. I think people not so interested to send mining equipment to different countries.
In Ireland all company which work with crypto have to be registered by law.

Hi,
Can anyone recommend some hosting companies? Need to host some miners.
Thanks.
Hi! Where’re you from? How many miners do you need to host? |

You should have a switchboard, in which there will be a 63A input circuit breaker, RSD, and then the wiring for your needs (most likely 9+ single-phase circuit breaker of 16A, each outlet has its own circuit breaker) and compliance with all the rules for the cross-section of cables and it is very desirable that the cables are copper.

Well, since my buddy doesn't know about bitcoin mining, and didnt seem to interested in listen about them... Maybe I should of worded my request differently. I should of asked for help on the setup. He said he knows how to do the box and everything, but do i want outlets, or pdu. I seen people have an ac display meter, where does that go before or after breaker box.
I'm looking to setup some s17s up to 10. So basically, its just add breaker box, i can add ac display meter, what gauge wires for outlet 8,10 gauges? then just a Basic 200V-240V/30A, (10) Outlets pdu? Not other goodies? I just mine with gpus till now.
what about a fused disconnect box like what you would use for a hot tub: that be for extra safety?
Also i asked the electric guy when he came over several times about drawing 30k watts, he kind of blew off and was like it will be fine, that why i kept asking. I think cause the way my lot is setup (double lot), we have a transformer that is being unused, lucky me.
You are lucky that you have an unused transformer, so you can get 30 kW, of course, if you agree with the power company. This company will install the main input circuit breaker for you (with your requests, it would be better if a 3-phase 63A). The rest of the wiring can be done by your electrician. Where're you from? |

It will be cheaper if you do it by yourself, it’s really easy and if you have some electrical questions, just ask. Bullshit. You are not talking about adding a few low power outlets to a room or opening up and working on a moderately low power (compared to commercial/industrial capacity) household breaker panel. The knowledge required to properly and above all - SAFELY - do the wiring for 10's to several 100's of kW of power is vastly different. Even more to the point usually mining farms are a business that should carry insurance - that is not going to happen if it has not been wired by licensed professionals. You are not good as electrician, safety it’s first place for electrician all time and no big difference of 10kW and 100kW, license is not for 10kW or 100kW of power. You can receive license for system up to 1kV(most popular) or for up to 10kV+, but it’s not a kW! Dude, you should take a look at folks previous posts before making a comment like that. I have been designing and building industrial power systems since the mid 1970's. I've done power for industrial lasers that pull over 1MW from what amounts to their own mini-substation. Yes licenses are geared to working voltage but the point that really matters here is what the source can supply to a short-circuit. Just look up 'arc flash hazard' to see the huge difference between DIY wiring in a house where the SCCR *may* be as high as 10kA vs what can can happen when the building service can supply that amount as a normal load. A good example of PPE that is required when working on the high energy areas of building power can be found here. For the vidiots out there here is some very graphic video of what arc flash can do. Point is wiring power for a large farm is NOT something that is DIY unless you know damn well what you are doing and have experience dealing with that kind of power. Haha, if you can't read a message, why are you writing? Just look how it's done and what's kind of plug extender is used. He can just change plug extenders for a few good one and save a lot of money for future(Even just based on cable cross-sections). You don't need any license to buy plug extender, if you don't know which type you need, you can ask seller in shop and check by searchs or ask electrician. You can do it by yourself just with parameters for your equipment. All work can be done by qualified electrician(INPUT CIRCUIT BREAKERS, JUNCTION BOX, CABLE ROUTING) and it should be done in buildings by qualified electrician, but according to you, the connection of new servers in the data center is done by an electrician, and not by administrative personnel. |

Hi guys,
Have you guys ever try to mine with couple of asics connected to the Internet via 4G phone network.
Is it reliable long term or some issues are to be expected and this is not a viable option?
Many thanks for your feedbacks.

Hi, I bought 3G/4G modem from AliExpress. I have 1 asic and 1 rig plus TV and all other stuff. Everything is working fine. Average ping for pools in EU is 50-60. Germany/France/Italy less than 10. USA/Australia/China 200+ |

Thanks a lot! I agree, there are many things that can be done to improve everything, but sometimes the desire to cut the costs wins  Very boring situation! I hope you can recover quickly from the losses you had. But I would like to make a suggestion, taking advantage of the fact that you will have to rebuild some things. In this case: Avoid using extensions! I would suggest using technical gutters (PVC-U Trunking), something like this:  You can see more explanations here: https://trenchltd.com/products/pvc-u-trunking.htmlI don't know this brand, but it was the only one I could find with information in English. This will help to reduce heat near the outlets and in turn reduce the risk of problems. It will be cheaper if you do it by yourself, it’s really easy and if you have some electrical questions, just ask. |

I hope you are already recovering your losses.
For the future, you have a free space on top that you can cover with a metal sheet that will insure you against water from above. It is better to do the wiring in plastic pipes, and I also see extension cords for 3 sockets, they can be used with fuses. Can you provide a photo of your electrical panel?
