I really want to know how you buy mining machines?

[MINER_STONE]

Ali? Ebay? Global Resource network? Or what channel? Can you tell me about it?

[NotFuzzyWarm]

The only reliable way to buy is direct from the manufacturer or their authorized distributors listed on the manufacturers website.
ANY other way means:
1. No warranty
2. Strong chance of being scammed

Amazon will protect against scams but the miners still will have NO warranty. Considering how often Bitmain's miners fail (and other makes but not as often) you NEED a factory supported warranty.

Bitmain.Com, manufacturer direct, as reliable. Purchased from since 2017 when reasonably priced stock is there.
   note : Their customer service (email response) has been horrible the last year. They used to be prompt and answer the actual question.

I can also strongly recommend Whatsminer.net (not Whatsminer.com). I have purchased from them in the past (new unit about 2 years ago) and just recently a Certified Used M30S that arrived within a week of purchase. That was unexpectedly fast. They are lacking in new unit availability (chip supply shortage), but keep listing batches of certified used. They are a US based factory re-seller. I THINK  only 1 of 2 official US suppliers.

I have also used Amazon, but expect to overpay. (Purchased from Unistar on Amazon in the recent past)


There is a number of threads with some reviews of sellers (mostly on Telegram) if you search the forum. I have one pending order I can't speak to reliability yet, but has been reviewed as a trusted supplier by other members, is Grace Zhou from minerexpert. Again, I can not speak to reliability myself yet, but have 1 unit on a future batch I have trusted sending my money to based on other forum members recommendations.

This kind of risk exists. What about buying second-hand miner machines?

The obvious question: why is someone selling their miners?

People like to overclock them with illegal firmware and then sell them off before the machines die.
Others put firmware in the miners so you are losing some of your mining.
Some well known sites that sell miners will also do this.
If there's some problem with the miner that doesn't happen all the time, people will sell these miners and claim they are ok.
Of course there's a truck load of 2nd hand miners being sold at ridiculously high prices also.

To be blunt, the 2nd hand miner market is higher risk.

The fact is no one mentions here where to buy but if you really want to buy directly from the manufacturer and verified distributor then there is a list here on the forum where you can see all lists of the manufacturer.

Check this Current List of Competitive Hardware

And also try to contact offordscott
He will help you to buy a miner and there are many miners you can find under his telegram account most of them are not well-known miners.

Yes, I know that there will be many problems, but the income of second-hand miners is the same as that of new miners, and the payback period is less. Is there any on the telegram? Can you recommend it to me?

If you are aware then you should be also aware of the warranty.
2nd hand units don't have warranty support so if you receive a defective one you won't be able to get support or a refund.

Anyway, about his telegram go to his website here https://www.scottofford.com/ and scroll down to find the telegram link. There are used and brand-new miner on his telegram and also try to contact him I believe he can help you look a good 2nd hand miner.

I have only bought my miners direct from manufacturers when it comes to ASICs. I dont like buying them secondhand without any type of warranty. Especially if you are buying in this bull run or over the last 12 months or so you are already paying a very large premium just to buy the machine and if you buy it second hand and something goes wrong on day 1 you have a very expensive paperweight if you don't know how to fix it yourself. I would recommend waiting for prices to come down or being prepared to have a longer break even time period if you want to have a little more peace of mind if something breaks you at least have a warranty to fall back on.

Is possible to buy mining machine's one after the other?

If we can buy our own mining tools for ourselves why mining industries is not as multiple as exchange?

The power supply that is required for mining of coin does it stay constant till 24 hours time?

[NotFuzzyWarm]

No idea what the first 2 mean but as for

The power supply that is required for mining of coin does it stay constant till 24 hours time?

yes miners usually run 24x7x365 and pull full power the entire time.

building mining gear is expensive.

designing the chip
designing the pcb board
and making it work
making it cheaply
making it run efficiently

all hard to do.

exchanges can compete more evenly.

I E 

  0% fee is as low as you can go
1% fee  is getting pretty high

so exchanges can pretty much match the rival exchange far easier than asic builder can.

Are there no sales outlets in your area selling used miner machines? Because I do not have, so I am very distressed.

[Bitcoin_Arena]

Ali? Ebay?

Must be on Amazon

I advise you to avoid buying miners from Alibaba/AliExpress, eBay or Amazon. There is a high chance that the equipment is faulty and you may not discover the fault until the buyer protection or trader assurance period is over after which you may not be able to return the product to the seller or dispute for a refund.

Always go for official manufacturer online stores or official resellers.
