Topic: Where can I buy miners? (Read 1699 times)

Every time I buy equipment, I need to take videos and photos, packaging and logistics of equipment and goods, etc. Every transaction is perfect

Just wanted to add.   Kaboomracks is legit.  You can find their listings in the marketplace section of the forum.
I ordered an S19pro 104 from them on 10/29.  It was delivered today, 11/24, and is up and running.

You don't get any ltc in this part of the forum ...

I understand all those points but as i have learned most come to this conclusion assuming one pays utilities.

if you get free electricity is mining then worth the investment? or would you still advise just buying crypto.

Another plus i like is not needing to kyc to get my LTC/btc

I'd love to have a place to physically go buy miners. It would provide much more confidence for me. I'm looking to buy my first BTC miner.

Miners (Bitcoin Mining Machines) are supporting devices for miners to mine coins by solving algorithms of virtual money systems and earn corresponding coins.
Mining machines: Dedicated coin diggers and self-assembled diggers.
If you do not have a lot of knowledge and mining machines and need a company specializing in mining to advise and set up for you
Investing in virtual money in general or investing in mining machines in particular is considered a risky investment, but in return, its profits are very large. In cases of high volatility virtual currencies, becoming a billionaire is achievable for investors.

Your math is correct, not sure how i missed the mistake in that article, goes to show that you can not trust the media neither the government.

If its only 1104 kwh then it can't be 10100 unless those are GPUs.

yeah retired gear pulling 1 kwatts each would be s9s. but the math is off. i dont think it was what they write
10,100 x 1 kwatt would be 10,100 kwatts

a drop or two in the bucket 🪣


if only 1 kwatt a machine then it was 1100 machines doing the 1100 kwatts

which is 12100th or 12.1 ph which is really not much.
still would be nice to see

i think i got the math right but maybe not.

10,100 mining gears that consumed 1,104 kWh according to "The Development and Reform Commission of Bayannur City in North China's Inner Mongolia", you can read more here

This can't be major if the numbers are right, 10k gears each consumes 1kw? what could it be? maybe an underclocked S9? so 12th per gear? 121ph or maybe 130ph at most? these are indeed a lot of gears for any individual, but is it worth being on the news given the size of the network and how tiny those 121ph seem? I don't think so.

well this is interesting but a link helps.

a lot of machines is ?

10 x s19 is 1ph not a lot
100x s19 is 10ph not a lot
1000x s19 is 100 ph not a lot
10000x s19 is 1 eh and while a lot still under 1%

15000x s19 is 1.5 eh and is 1% of the network

it would be 3.4 x 15 = a 51 mega watt plant I am thinking it was not that much.

Link would help.

Last night, China's Inner Mongolia seized a lot of mining machines. It is expected that the btc will continue to decline for some time in the future. This is a very unfavorable situation. As a miner, this is bad news. I hope that a better development method can be proposed.

I think it is possible to conduct unsecured mining directly in the wallet. 720 computing power

Do you think we will see a rise in the stock levels of crypto mining hardware on eBay filling the gap now that alibaba is leaving the scene.

China continues to block cryptocurrencies in all directions, so from October 8, 2021, Alibaba will ban the sale of equipment for mining bitcoin and other cryptocurrencies on its platform., the announcement was posted on their official website, the truth is that there were too many negative reviews earlier about buying equipment there. https://rule.alibaba.com/rule/detail/11004645.htm?spm=a271m.8038972.0.0.22286d82hvTv3v

You can look for them in international  markets.And global e-commerce  they are pretty easy to be found there. If you order there they will ship it to your hoke adress. See review before buying

East Coast Mining (https://eastcoastmining.com/) offers very good prices, includes warranty on old and new miners, and fast shipping.

http://ydminer.com/en/

add this number on wechat and ask for the list (prices change everyday):

 i paid usdt and I've received what i've paid for.  price was ok.

This is how sellers on Alibaba/Aliexpress usually scam you, they don't just ignore you and walk away with your money as that will bring them troubles, instead, they send you a terrible product that usually just doesn't work as advertised, in many cases, they might just send you a different product.

The problem with buying mining gear is that the seller needs to be trusted, they all offer you a Video-Proof showing how the miner works perfectly, but these videos can be easily faked, and then they will blame the shipping company or anyone else and insist that they tested miner before shipping and that they have the video tape as a solid proof against your claims.

Hello dont buy from DEHAN NETWORK TECHOLOGY ,its scam I recently bought from them 4 miners paid 7400 usd and they sent me all the garbage that had them all repaired and with missing radiators on the processors in addition some radiators were glued with silicone, I also have photo and video but I don't know how to load them here on the site, you can find the company on ALIBABA

Grace has fairly good prices, I rolled the dice and ordered an S19 from her.  Fingers crossed!  Now to wire the 220v outlet..   

The WeChat/Whatsapp, pay with crypto is a pretty big path to getting scammed (happened to me).

I source mine through Alibaba.  I have found 3 suppliers that have good prices and services.

Ningbo Zanboo International Trading Company - ask for Tracy - Bought many types both new and used from them.

Shenzen Letine Technology Company - ask for Shira - Bought alot of new BTC miners from them.

Shenzen Changcheng Technology Company - ask for Susanna - Bought a used miner from them.

I use Trade Assurance.  Ningbo seems to have the best prices.  Changcheng has the largest selection of used miners and is a decent price. 

Hope this helps folks.

Well since nicehash has always blatantly lied about their returns vs mining elsewhere, I'd suggest to look at a calculator elsewhere.

This link is a good starting point

https://www.nicehash.com/profitability-calculator/

You are asking a personal preference question.  What defines "best"?

There are some basic considerations based on your parameters?

1.  What algorithym do you want to mine?  SHA-256?  Ethash? Scrypt? there are many, and vary based on which coins you want to mine.  If you know you want BTC, you can mine either BTC directly with SHA-256 miners or indirectly by mining other algorithyms and buying BTC.  You have to decide your approach, to each their own.

2.  New or Used?  New miners are scarcer because of demand and production limits, and prices are higher (they dropped recently but still high comparitively).  Lots of 2 - 3 year old used miners coming available as miners switching to more high performance miners or are just shutting off.  Many times, when you buy a used miner, they will actually take it right from the farm and ship it to you.  Beware the dirt and cleaning required but don't take it apart yourself unless you really know what you are doing.  Running a dirty miner isn't optimal but it isn't unheard of.  Also, used miners are a bit more fragile and they may break in transit so you may get a DOA unit.

3.  How eco-friendly do you want to be?  I look at joules to hash ratio and look for the higher efficiency miners.  The S19J 110Th is slightly more efficient than the S19J 100Th from a power consumption, production perspective, but it is more cost up front.  I ended up getting the 100Th but am still debating that decision. 

4.  How much money do you want to spend?  Some small miners (Innosilicon T2T - 26Th) are selling for $1,000 new straight from their website, while used miners are much less (found a T2Tz25Th for like $700).  If you are just playing around and trying to learn, a few small / older miners may be the trick for you.  If you want to start serious mining, that is a different course and cost level.

5.  Environmentals are important to so what is your situation?  Some ASIC's run on 220v so if your location (house/apartment/etc) does have that, you are in for an electrician bill.  Some others run on standard 110v  so figure out your power situation.  But one thing an electrician can't solve for that all ASICs have in common.  They are loud and hot.  So if your spouse likes a sauna and some really nice 70db white noise in the background, you may want to find a hosting location outside of where you live.  They will solve the power, heat and noise issue all at once.  My wife is tolerant enough to let me test the ASIC rigs for a day or two and then off to the hosting location they go!

6.  Are you just in it for the profit or are there other considerations?  Each algorithym produces different coins, which have different values that change every day.  Some miners are at the top of the profit charts one day, the market changes and they become mid-pack.  Asicvalueminer.com or whattomine.com or others can help guide you but set your approach first and then find the miner(s) that fit that strategy.

Any other thoughts on key factors when picking an ASIC miner? 

My choices for ASIC miners are S19J 100T for SHA-256/BTC, HS5 for Sai/Handshake, A6+ or LT5 for Scrypt (still searching for a few but those are tight), just got a Z15 for Equihash and I wish I had a A10 Pro+ 7GB for Ethash, but those are pretty steep.

The used / smaller units are a whole other story so no recommendations there.

Now you are just taking the fun out of it...

But your points are extremely insightful and valid.  Want to buy some ASIC mining rigs (so I can go buy BTC?)   

That $6,500 100TH/s miner costs (current BTC price) 0.2 BTC

PPS per day of 100TH/s is ... 0.00063075
(and it's quite reasonable to say PPS, not higher, since you will have some combination of pool/miner/txn fees)
19.9T diff gives: 0.2 / 0.00063075 = 317 days.
Now that 317 days is FAR from realistic since difficulty usually rises, it's a major under estimate.
To assume that difficulty wont rise over the next 10 months would be foolish.

Difficulty today is 19.9T, difficulty 10 months ago was 17.6T so that's a 13% rise ignoring why it's dropped over the last 2 diff changes.
The 19.9T is due to miners being switched off in the last 6 weeks, that will mostly be on again well before 10 months from now.
The highest recent diff value is 25T only 6 weeks ago, so it would certainly be higher than that in 10 months with miners coming back online and new miners coming online.
But just using 25T, that puts the last 10 months rise at 42% ...

So if instead we used 25T (ignoring any rise) as the PPS value, that gets 0.0005019730957 per day or 0.2 / 0.0005019730957 gives 398 days.

The sites you are using completely (and incorrectly) ignore changes in difficulty for 2 reasons:
1) No one knows what the difficulty will be
2) They don't give you an option to guess or estimate it (like my page does )

That also ignores all the time and cost of running the miner for 10-13 months, so that extends it out longer also.
Then if you have 100 miners, what % of them are actually going to run 24/7 for even 13 months?
Certainly not 100% so another extension to how long it will take.
... to just break even ...

Now if you are gonna make the even worse assumption that you can multiply that 3X for 3 years (as you've stated) ...
What was difficulty 3 years ago (even using the current 19.9T) ... 5.1T or a 290% increase in the last 3 years.
So that completely blows the 3X number out of the water.

So diff increase, power and paying someone for the 1 year+ of time looking after the miner, is expected to be more than 13 months, and ever so likely to be a lot more.
Maybe 2 years is a reasonable guess? But then you have consider how high the difficulty might rise in 2 years and that could extend it out even further.
... again ... to just break even ...

Or simply just buy BTC, as I mentioned in my quote above, and ignore these running costs and difficulty changes.

Edit: and in case you didn't realise, the last 8 diff values have been:
21.4T 21.9T 23.1T 23.6T 20.6T 25.0T 21.0T 19.9T
(the next one could be as low as 14.9T ?)

Kano,

Not to debate too much, but I am finding your point about miners costing more BTC than they will ever mine a bit of a challenge.  I am using a USD based payback calculation, and whether the miner costs $1000 (T2T 26Th) or $6,500 (S19J 100T), the payback is about a year.  Definiately use asicminervalue.com or whattomine.com to help figure out the timeline.  Since miners hosted under adverse conditions last about 2-3 years, that is still 3X over time, even with pool and electricity.  I do very much agree its an over time thing tho.

I am finding there is a big mindset difference between people who like mining verse those who are trading.  Whether its mining to sell or mining to accumulate, its more of a long term, certainty play on gaining BTC (not necessarily the USD or EUR or ? equivalent).

I will add, since this thread is full of it, people reading it should make sure you check other sources for the reliability of web sites posted in this thread.

There are too many posts here by people who created an account to just post here and recommend a site.

Would you send thousands of dollars to someone that some random guy on a street corner, that you've never met before, recommended to you the only time he ever said anything to you?
Of course not.

There are a number of posts here from new accounts that scream 'buyer beware'

It doesn't save you anything to buy from a reseller in the EU, they have to pay the VAT and customs when they bring the goods in, so they are just going to pass the cost on to the you with extra.

Any trusted seller in E.U? To save customs?

I have got all of mine here ,. They are based in Singapore but ship to any address worldwide . I have had shipped to 3 different countries , i would highly recommend  .

Lobo,

I am about 1/2 a step ahead of you and went down the dark path of scammers.  I went to Alibaba and found several vendors who have new and used rigs of various makes and models.  I have established a good relationship with two now who have sold me rigs (and delivered) pretty quickly (thanks to DHL Express).

There are a lot of scams out there for sure, I got bit.  As an FYI, they follow a similar pattern.  Attract you with an unrealistic price via an advertisement on Globalsources or Alibaba, get to you to talk to them via WhatsApp and then ask you for a Crypto payment which will get you a 10% discount.

Some later come back and ask for shipping or insurance, which should be negotiated up front.

Either way, don't do it.  Use Trade Assurance which is essentially an escrow service to protect you against giving money directly to the scammer / vendor. 

There is a lot of used equipment out on the market right now since most new are getting snapped up quickly.  Prices are high, even for pre-orders which if you want new is probably the best way to go right now so you have to be patient.

Let me know if you want contacts and I can pass them along.

David

LOL.

There are a dozen members who sell mining gears here, and another dozen that offer escrow, you need to be insane to think that I have some sort of a secret deal with thousands of people.

I did not claim that you are a scammer despite the fact that I am seriously leaning towards that fact, what I said, is that since you are a newbie here and have no reputation you should accept forum escrow (a service which I don't provide FYI), but you insist on selling your gears without the use of escrow and expecting people to send you money first. if someone is stupid enough to do so, be my guest, I am trying to help YOU sell your gears if you are legit, nobody in their right mind would send money to a random newbie.

If you want to sell your gears, offer the use of escrow, this isn't a command, I don't own the place, I am giving you free advice and you are free to accept/reject it.

We have plenty of stocks available for sales and 100% legit.

You may find our Amazon Store :

http://www.amazon.com/shops/AHQCHVKWA3DTN


or directly order from our store:

https://cryptozen9.com/

Order from our website will get a discounts and you payment will still be protected by Paypal.


You may whatsapp me at +60129358963 for more information.

Sweet thanks - will look into it.

Thank you, one webstore you listed above is  hard proof that belong to one of my partner. ( I have maintain that website from very beginning until now, that domain name is also registered by my hand).

I was show some sales record from backend  to one legendary member by personal message 2 days ago.

Found these on asicminervalue
https://shop.bitmain.com/ *Official seller
https://www.innosilicon.com/ *Official seller
https://coinminingcentral.com/
https://akminer.com/
https://www.goldshell.com/

I used https://www.cryptominerbros.com/ before, worked great!

By the way, don't misguiding people here that a seriously online seller accepted escrow deal, that's is joke, at bull market miner are Very tight plus coin value fluctuation is too quickly , not easy way or source to buy it and if you have miner in hand buyer will desperate pay for it.

Why should the seller crazy accepts Escrow? his brain has problem?

Yes, We are scammer, thank you for your compliment.

So like you recommending someone else miner seller are not scammer? who knows the back deal between you and them, As a bystander do you think all folks here is blind?

I like competition fairly, but I don't like someone like you pretending you are fair to judge someone just want keep some shit that seller feeding you. ( can you swear they don't give you some benefit behind?)

Really?

This does not change the fact that you are trying to sell your mining gears here without accepting escrow and without having any history around here, with all due respect, to me, you are more likely to be a scammer than a legit seller, and I am sure most folks would agree.


Alibaba is far from safe, while it's unlikely to be directly scammed, the gears most sellers on Alibaba will send you will be either not what you paid for or defective gears, getting the seller to refund you the money will be a nightmare, and the safe-trade or trade-assurance b.s will only work if you are a Chinese, it will be extremely difficult to get Alibaba to stand with you against a Chinese seller, if you want to take that risk, it's on you.

if you really want to buy please check below site, its safe.

A miner at any time, will usually cost you more in BTC than the BTC it will make mining.
At the moment that is definitely true, miners are being sold for WAY more $->BTC than the miner will ever mine.

Add on top of that the cost of running it (time and electricity)
Also, the BTC will arrive slowly over the following year or more and thus if there is a peak at any point where you want to sell the generated BTC, it will of course not be the total BTC.

If instead you just buy BTC, you will get more BTC, you will get it up front, and also be able to decide when to sell that BTC at a profit.

Yeah I agree, I mine BTC because of rentability. If BTC drops, I will keep my rigs powered off, and power on them when BTC will be higher.

And your reasoning doesn't take in consideration solo miners : if you have enough power to be able to solve blocks sometimes, you will earn more than you can ever invest in general. Take in consideration the fact that the ASICS doesn't lose value with time (when they are able to work), it depends of the BTC value.

So the magical formule could be : buy cheap asics when bitcoin drops, mine, and when bitcoin increase a lot, sell them. You will have BTC for the price of electricity, with free (and some beneficits) asics. In my case it works great ! (I personnaly don't pay my electricity at a high price, I know that this formule doesn't works for everyone)

that's will be a gambling, however mining also kind gambling, just slow than invest buying bitcoin.

Think about it again. A lot of data shows that if you invest the same money in buying bitcoin, you can earn more than mining it

 Obviously this forum not my selling main battlefield, as experienced we have more efficiency way to selling products and service.

By the way, just reminder you that our top sales value is one order around USD 90K, those guy will help to expanding our sales because they will recommending customer to Us rather here to face a lot of risky to explain too much.

Almost all miner is come from China, specially from Shenzhen, as real have miner stock in hand, we are some source of supply for the deal/ agent / distributor around this world.

As professional buyer, I don't think they are going to buying miner from Alibaba, specially for some high number miner.

Also most of those seller from Alibaba is not professional on cryptocurrency area, they are just young girl only speaking english.

We have own hosting farm and real first hand miner in hand, we also specify is Miner if are used on store clearly to avoid any mistakes.

We looking for long term cooperation.

Actually the most highest order is around 90K USD direct paid, I show you screenshot that buyer from a north america country.

We have miners in hand as first hand so should be source of supply.

I've spent hours on Alibaba asking sellers about Mininers and looking for websites, without any real progress. This sector is full of moneygrabbers and lying people, read many bad reviews about shops not delivering or faulty equipment. The prices are too high and the machines are lied about their specs or they send old used miners when they upgrade their machines resulting in faulty items. "Sellers" don't have stock. I'd be surprised to find an honest shipping website, they don't exist.

He sent me a PM, saying that akminer is their another store.
Well, I don't know them either.

You said:

I asked:
Could that same legendary member please post here?
I'm eager to see who it is.

I think it is reasonable to demand some hard evidence about you, because especially with the current prices, you are close to same price levels as a car dealer. 20k USD is big money!

There is no such thing, you are guaranteed to get paid the amount agreed on when the escrow is done with their part, the price fluctuations are irrelvent.


Anyone can create such a list, it means nothing and it's worth exactly nothing.


Account rank can be irrelevant, many of the old era legendary accounts changed hands a dozen times, I am not sure why do you have to mention that your alleged clients registered here before me, it's off-topic, but just to piss you off I would like to let you know that I am top 10 most earned merit, DT member and highly trusted, my account is more trusted than a dozen other legendary accounts combined, and even with that - I don't go around the forum selling mining gears without offering the option of escrow.

I do not care who your clients are, if you are counting on getting a vouch from 1 or 2 random legendary members that nobody around here trusts - it will be useless, those accounts are sold for pretty cheap all over the internet, if you are going to bring someone here to vouch they need to be trusted, there is probably less than 50 members whose vouch will count, the rest will be useless and you still have to use escrow if you want to sell your stuff here.

I have send you personal message but need waiting 10 mins due to restrict of posting message for that proof.

But obviously you are real legendary guy.

Would some of those legendary members please post here...
until that it's a claim without proof.

To be honestly, No offense that some of our clients here was registered earlier than you which their level also legendary.

I posted some screenshot photo of our another store shows everybody here that we are trusted/ reliable online store, We have really stock if www.minerbrother.com store offered it.

I don't know someone else, but from our online store that we show our real company information that can be tracked: https://www.minerbrother.com/contact-minerbrother/

One experience share with you, if one company has USD A/C from China, it's should a real company indeed.

Never heard miner seller offer COD or Escrow due to coin value fluctuations too fast.

We also running another miner online store,  since this April until today at least $800,000 deals, all buyer buying Miner online directly, in some case I can bring some buyer as reference to potential buyers, some users should still in this forum.


Here is the deal/order records screenshot below for reference to you and everybody here.

https://imgtu.com/i/g2nvX8
https://imgtu.com/i/g2ukpq
https://imgtu.com/i/g2nznS
https://imgtu.com/i/g2nj6f

But nobody here knows you, it's safe to assume that it's pretty risky to deal with you, the majority of asic miners sellers are scammers, so this is nothing personal, you should offer the use of forum escrow or cash-on-delivery if you are serious about selling your miners.

Hi Lbogris:

I have total 200PCs used Antminer L3+ that you can buying directly online from: https://www.minerbrother.com/product/used-antminer-l3-shipping-within-5-days/
 and Used AntMiner S9j 14TH that you can buy from directly from online  https://www.minerbrother.com/product/used-antminer-s9jpsu-included-shipping-now/

we accept crypto currency paying and there is some other Miner available you can check with https://www.minerbrother.com.

Yup, Oleg is a fine gentleman. I had a few trades with him in 2019, all went smooth, not the best in terms of price if the order quantity is small, I can also vouch for https://t.me/minerexpertsales (graze), she is an honest seller and prices are ok for small quantities, so always check with both.

Check this thread below for manufacturers and official distributor

- https://bitcointalksearch.org/topic/current-list-of-competitive-hardware-january-2020-5045732

And I think you can also buy some new and used miners from https://www.zeusbtc.com/

I can vouch for HashExpert, I've used them several times with no problems:

https://sales.hashexpert.net/

There is also a list of verified venders here which may be useful:

https://docs.google.com/spreadsheets/d/e/2PACX-1vSJIVfyPhI_E4IdVeU_VcZGdnrS8VcHfIxEtXD_60QJ0JCpfPRy6uY85yNbp2EzQAonLxDN2uZfrrLi/pubhtml?gid=0&single=true

Sellers I've used that are genuine, but not a good service (I DO NOT recommend):

ITGuangZhou Group (China) - I bought 20 x S17 Pros, sold as working 100% but arrived with several dead hashboards that have been diagnosed as unrepairable (by HM Tech in USA). Basically told it's my problem as they were working before they sent them, then after some negotiation said they would compensate but then offered $300, which I refused as it's an insult...

Coinminingcentral (UK) - No problem as such, just very unprofessional, poor communication, prices not updated in timely fashion etc. Appears to be run from a domestic address

Hello,

can someone tell me which trusted sources have new or second hand stock available? I see a lot of scams out there

Thanks
