Topic: Is BITMAIN a trusted source for purchasing mining equipment? (Read 6396 times)

No. Even today, they're lying about S7 parameters.

https://bitcointalksearch.org/topic/antminer-s7-473-ths-025-jghs-batch-19-releases-tomorrow-1511522

The one time I ordered direct from BitMain, the order arrived in 3 business days via DHL.
Very competative on time with most folks I order stuff from in the US (Newegg can beat that if they ship from their Indianapolis facility, but usually takes a day or two longer since I usually use their "saver" option).

My first 2 s-9's arrive in a day.  I will let you all know how they setup in the solar array.

I decided to order 2 more.  So I spent just about 8.3k  for 4 miners and shipping.

Answer: yes.

Shipping time from Bitmain in China is about as fast as anyone in the US. My new S9 shipped later Sunday and it's expected tomorrow. Occasionally it will get held up in customs for a couple of days, but I only had that problem when I bought 35 S5's all at once and the customs folks didn't know what they were.
When I buy 1 or 2 units it takes about 48 hours (West coast).

It depends if you want faster shipping or not. Sometimes I will buy from websites like eBay because they ship from the US, not China, and I'm willing to take the extra cost for saving time. Warranty has never been an issue for me even buying from eBay or Amazon. The only bad thing is, people resell for a higher cost there, and if you're willing to buy it for more, but have a smaller ship time, this is for you.

Bitmain's trustworthy enough that you can safely buy from them, unlike BFL which ended up not sending it's miners at all for many people. For now, it is safe, but watch out , because as Bitmain becomes more of a monopoly this could change.

yes i do, bitmain is old support for hardware of miner and its costumers there are not find problem.

Buy Directly from bitmain IMO, warranty can become an issue if you get it from someone else.

I have bought 4 S1's and 2 S3's from them , all worked great, no issues.  S1 is still hashing (more so to prove out how much of a beast it is ) about 2 years it's been going.

 You forgot a few.

 Innosilicon
 LKEtc (and BW.COM by extension)
 Gridseed/SFARDS
 Alcheminer

 Too early to tell on the X11 miner makers, but all three of them so far seem to have actual legitimate products, abet with some issues here and there.


 By Cryptocoin Miner Manufacture INDUSTRY standards, Bitmain is well above average on reliability and trustworthyness on gear sold, so-so on warrentee repair.
 By the standards of MOST industries, they could use some improvement across the board.


 Innosilicon has done sales to small miners also, especially those "Farm Boy" units that appear to have specifically targeted the small miner.
 They also made miners that had a VERY VERY GOOD reliability record - better than anyone else in the industry except LKEtc (then again, there seems to have been some cross-manufacture and/or cross-design on some of that gear given the Dragon and Terminator designs and LKEtc using Innosilicon chips IN the Dragons).


 Sadly, most other "direct to small miner" companies have either not done well in the long term even when they had a good product (Spondoolies as the best example) or were outright scammers/liars/incompetant (can YOU say KNC and Butterfly Labs, among other WORSE examples?).

Wow. 900.
I got customs hassles with just 35 S5's last year.

I can say my experience with Bitmain has been 99% good since my first S3+ purchases.

The 1% is a set of S7 boards I sent for repair that apparently were lost. I shipped EMS and tracking says 'delivered'. But Bitmain can't find them.

As for price, you can choose to mine or not, based on price. If you choose not to, and so do others, the price will drop. It's sad that only Bitmain seems to care about selling to smaller miners but I'm glad they do.

Op you can lock thread and then do a self modded thread.
The problem with your question is most if not all ASIC  builders have done wrong to some of us.

So people will make pretty nasty remarks about them.

Should have made it "self moderated" then   

Live & learn 

If you buy an s-9 or an s7 or and s-7ln

Pay with btc fast with proper fee to the blockchain

Answer the email they send fast.

You have a 100% chance of getting the gear.

Based on my 50 purchases to New Jersey

You have a 2 in 50 chance for bad or slow gear.

Based on my 50 purchases.

If you get bad gear they are slow to fix it.

Avalon purchases I got 45 Avalon 6s or Avalon 4s

Sent to me in NJ
0 were broken
I broke 1 they were fast to sell me the repair part at a good price.
Note I paid for this since I over clocked and broke the gear.

Long time ago Avalon did a lot of people wrong.

I did not purchase at that time so I do not hold it against them.

But they have no new gear right now and they just cut a deal with a big Chinese power company. So I do not know if they will sell gear to us any more.

I have no problem buying from them and if they want me to run a group buy like I did in jan 2016

I will do so.

Thats exactly what all my comments are about. Personal trifles aside. They deliver, but if you get a bad unit, tough luck. Also i've bought units that were obviously used as they were full with dust. Its not that they are scam. Not at all, its that they have poor ethics. They could have at least cleaned it, but no.

If you get a good unit. Good for you, no problem. If you get bad unit, they will tell you they give you compensation, yet some people have been waiting for months/years for compensation and never got it.

Or what they get is a few months later a shitty worthless coupon.

This topic is about the trustworthiness of BITMAIN.

This is a thread about reliability and you didn't expect arguments coming? 

Please take your arguments to PM because I want this thread to be purely informative, not arguments.

No, i'm saying they're in China, thats far, it cost more to ship back a controller, than buy a new one. In which BITMAIN refused to honor the warranty unless the defective controller was sent to them.

Stop twisting your version of what i said in favor of you argumenting and harass me on forum, while its purely off topic. If you have an issue with me, kindly take it to PMs.

I paid with USD for 5 miners at the same day from 2  different bank with 3 transfers.
All of these were  transfers,  which was missing about 26-40 USD bank fees, which I paid with BTC later.

For two transfers Bitmain open 2xTicket, for third transfer, I wrote them himself and got  the payment adress and   amount of BTC what i have to pay extra. I made three payments and send 3 emails with paiment and order number.

Just someone forgot change from UNPAID to Paid and this is in no way my fault. The remaining two was marked paid one not.
...
Why do I pay less - because if I put -I will pay all expenses - Bitmain is still every time missing about 17 USD. And the transfer will cost me 15-25 euro. (Depending on the Bank.)

When I choose a normal service , I pay only 5 euro for transfer and missing is 26-40USD Depending on the Bank.
   Therefore, I will no longer use the service-  Choose "PAY ALL FEES" when you wire payment
Because is still missing 17USD and Bitmain wants this amount in BTC

Sure I'd say Bitmain is legit up to a point. Well all of the companies are legit up to a point. It's your choice who to trust.

Yes - They are quit for  a long time to the Mining Buisness like Bitcoinbrothers or someone like this

For.

My dissertation involved spending months looking at legislation, of which the majority was mandated at the EU level via directives which had to be implemented into UK law regardless of if it made sense or not for us. A recent horrendous example is VAT MOSS which is literally the dumbest thing you've ever seen and if any of my businesses touched it I'd just close them rather than comply. On top of that, opportunity arises out of uncertainty and its very likely we'll be able to negotiate far better trading terms with states individually than as a lump sum.


Yes, although you'll buy from their distributor rather than them directly now.


Probably uncertainty in both btc exchange rates, mining difficulty and miner prices.

Then let me ask about Avalon Project. Are they ok to buy from?

May I ask what do you mean by this?

They are the best or second best  in terms of you will get working gear.

Bitmaintech

Avalon or Cannan

Bitfury is on the list  but you need heavy money and must buy big.



At this moment in time  only choice from above is bitmaintech  since they are the only one selling gear.


I currently have 6000 usd in orders with bitmaintech.

and if Avalon / cannan had new gear for sale I would buy 6000 from them.

Bitfury has no new gear and I would not have enough money to buy from them.

So if you want to buy today you only have bitmaintech to buy from.

The big problem they have over the years is if your gear breaks they are poor at helping you get it going again.
The good is they get it on time most of the time.
They gear works most of the time.

So if you buy 6000usd  like I did I know that it is more like 6200-6400 in terms of real price due to slow repair risk.

With 3 pieces for 6000 I am hoping they are all good and the premium of 200-400  does not come into play.
I have order 40k in gear from them  more then 50 items since dec 2013.  every item was delivered most on time or early a few late.

1 item was doa  and it was a struggle to get repairs.
1 item was a very poor performer and its was a struggle to get a partial refund.

in both cases i did get  my repair/replacement >>> about a week but a large miner did the replacement not bitmaintech ,bitmaintech would have been 1 month

 and my partial refund >>took about 6 or 7 months

So I rate bitmaintech better then okay to buy gear from.

We bought 900 antMiner S7 from them without any problems. Except maybe customs asking WTF.

You're suggesting that a company is implicitly unethical because its Chinese, not only is that racist but nearly every example of mining companies has shown the opposite.

"Western" companies
BlackArrow
AMT
HashFast
Technobit
CoinTerra
HashCoins
BitMine
BFL (lol)
SpondooliesTech (unpaid debts etc)
KNCMiner
XBTech (Russian team in CN)
BitCrane
GAWMiners
Bitfury (the exception)

Asian companies
RockMiner
BTCGarden
Canaan Creative
Bitmain
ASICMiner (the exception, and one man)

You paid in USD for that transaction, and apparently didn't pay enough and had to send BTC to cover the additional USD value. That is something totally different, they have to manually approve your transaction and will get to it eventually. If you send an email you will probably get it resolved faster, but you should really have sent the proper amount, unless of course you are saying they changed the price or failed to pay the wire transfer fees.

Why ?
https://bitcointalksearch.org/topic/scam-or-unauthorized-representatives-alert-1507845

Bitmain is reasonably legitimate.

 Doesn't mean they don't ever have issues - but ANY large company has issues sometimes.

 They're a TON more legitimate than a majority of folks that have claimed to be "miner manufacturers" - though that is a VERY low bar to clear.

Yes, you can trust BITMAIN.

Oh, so this is what the huge drama train against you is...dogie. You attacking people on the forum, that is.

I dont care for your attitude, so i would appreciate if you would kindly bring it somewhere else. Now if you're here to discuss and not just bitch because you have a bad day, i will elaborate on what i'm saying and would then like you to keep your moronic comments to yourself ;

As far as dealing with a company in China; I'm saying the North America consumers rules don't apply there. I'm talking about ethics here, not ethnicity. Jeez. So by dealing with Bitmain IN CHINA, you have to deal with their shitty ethics, support and services and tough luck if they rip you off. (personal experience = they don't care about you or respecting your consumer rights)

Thats not racism. So if you think what i said is racist. I think you should question yourself on the topic of bigotry.

Next time, try to make a minute effort into staying on the topic, instead of going all "I'm an American, wha whaa Racism" we dont even have Racism here.

I'm not sensitive at all - I pointed out that something really dumb he said was really dumb. While using no evidence he stated that Chinese were implicitly scammers while the actual facts show that its us 'westerners' are the ones to have churned out 99% scam companies.

Dubious ethics like potentially selling used PSU's with their s7 LN...and their hardware is definitely overprice. I think it's around 4 months ROI and that's if the difficulty stays still. They're the best though and they may be the only people left in the future so cuddle up to them

Such a sensitive snowflake you are. Should really consider chilling the fuck out sometimes.

You remind me of Social Justice Warriors today that get all raving-mad when people point out facts that run counter to their world view.


I guess you haven't read that one old Greek story about some wooden horse and a fortified city ?

There is no such thing as overpriced, it's all about supply and demand. It's not even as if a Miner is a must have product, ownership is driven mostly by greed and prospect of making an  easy Buck. If people think they are overpriced then stop buying and they will reduce the price.


Rich

Just the way it works here in Murica BTCland(they were all just ripoff artists or became such after finding out they can getaway with anything).....fleece the nerds & geeks,who dey gonna call??

No one,just like in Sweden 

Bitmain WILL ship what they sell (they are overpriced,but what canyado),if you buy from them & not a scammer posing as them.Check here BEFORE you buy from anyone!!!!!

All USA based mining hashware providers were scammers, eg BFL, Cointerra, Hashfast, etc. America is no longer competitive due to massive regulation, taxes, and socialism. I would be more skeptical of an American company than a Chinese one.

Extremely racist to classify any country like that.   Bitmain is very trustworthy I would say going back looking at all the companies that have come and gone.  So far they have always delivered the miners I order.    Even the little known L1 they decided not to do they gave us refund plus some if I remember right.  So have always came through and continue to sell to consumers.

Look at so many other companies like BFL (which was US), Hashcoins, TerraHash, Insert ton of pre-order companies here X.  Bitmain look very trusted if you go back though history as far as I see providing so many generations worth of gear.

What, really? It could get, and has frequently gotten, a lot more racist around here.

The points do stand that Bitmain has dubious ethics and rip-off prices, but they also reliably deliver on their promises and don't advertise vaporware. They're currently the best option.

As far as a post can be racist, that's racist.

They have dubious ethics and rip-off prices, but definitively legit, as far as a company can be legit in China.

Oh for sure. They're by far the best company out there for hardware right now with their new s9. Definitely trustworthy. I recommend waiting about a month because some very crazy things are going to be happening and it's best not to expose yourself to that much risk.

I'm new to mining and am wondering whether BITMAIN is trustworthy or not.

Any recommendations will be appreciated.
