Yey congrats to Shitmain... They managed to even turn miners against each other.


Just turn your whole GPU farm to mine bytom, just because you are angry at Bitmain... no matter that it is more profitable to mine Ether, not even considering the other altcoins out there. 

FUCK BITMAIN!
FUCK BYTOM!

What is the point to mine Bytom? Even with GPU... Simply it is not worth it! There are far more profitable options.

Damn, you are a smart man! RESPECT! I feel so dumb after reading this

And no I don't say it with Irony. Thank you sir!

Decisions, decisions. Of course you take the risk with any crypto related stuff Coins/mining hardware etc.

Lets take Antminer X3 (cryptonight) that mines many coins for example. The forks were totally expected ... another asics invading the cryptonight arena also totally expected. Yet some people took the opportunity and bought it. Probably some made profits some did not. I don't know but is totally their fault.

Was it expected that all Crypto will decline in value ... YES.

However the situation with Bytom and Antminer B3 is different. There was a huge premine and long token history of the coin.
Bitmain and the creators of the tensority algorithm made very sound presentations of how they will change the AI development blah blah.
Bitmain advertised the B3 as the machine developed specifically for Bytom with the help of the developers of Bytom and claiming they are the only one that will be able to mine Bytom.
Was it expected that other players will join in with their ASICs based on tensority - totally YES! Was it expected that Bitmain will flood the market with Antminer B3 ... or release a more powerful miner very soon after the B3 - YES.

However to be beaten by general purpose hardware - GPUs in terms of performance and efficiency (and to make it worse -- 2 years old hardware  ). Come on that is lame.
Bitmain has a 5+ years history making ASICS (SHA256 miners were single algo once). So you and they are telling me they made an ASIC based on Tensority Algo together with the developers of the algo and did not care to test it VS GPUs ( general purpose hardware that you can use for games, videos, password cracking, porn and whatnot
Reading headlines like Bytom cracked by GPU miners makes me laugh so hard (cracked by at least 3 independent developers in less than 2 weeks the Antminer B3 was made available)

The Bitmain could have just made a simple test to see how their hardware scales vs GPUs in terms of performance.... AND THEY SURE DID.
But they sold the miners anyway ... so this is called SCAM.
Why did they completely removed the Antminer B3 from their website?

BTW i have 5 Antminer A3 ... also single algo. They are losing me 2$ each (10$) per day ... sold for as little as 145 GBP at ebay bundled with the PSU
Wasting ~8KW 24/7

Am i blaming Bitmain? Maybe a little for flooding the market, but so did the other ASIC manufacturers.
Would i blame them if there was a fork? NO? Why? Because they delivered what they promised. An ASIC miner that is doing its job. Being more efficient than the General Purpose Hardware.
Innosilicon and Halong both have miners that are 4-5 times more efficient. But are/were priced accordingly of course

Of course it was a big risk buying the B3 ... but Bitmain are to blame because they failed at doing what they do best - ASIC miners.
They don't just do hardware.

But that will cost them a lot, they will lose a lot of buyers. Since the last few miners they released were total disaster. B3 being the worst of their mistakes.

P.S. Pictures and review of the insides of B3  https://bitcointalk.org/index.php?topic=3870665.0

It seems you are having extremely bad luck I feel sorry

--------------------------------------------------------------------------------------------------------------------

Thank you very much for your feedback which I've already escalated up to our management this morning and we really do appreciate your comments and information very much.

This means new products may quickly be challenged by products that are faster or more efficient. We trust our customers to follow developments and make sound purchase decisions based on their specific needs. There are still valid reasons for choosing the B3 ASIC miner over GPU mining.

You made some salient points in your email, but we cannot address them without getting into a discussion of our internal development processes.

We understand your position and would like to thank you again for your valuable input.

Dear Bitmain,

I feel somewhat cheated ... I paid $1322 + 20% VAT ($1600 total) with a coupon (regular price was $1672 + 20% VAT)
And this so called ASIC Miner does 1000H/s per 380W
GTX 1080TI for $800 does 1000H/s per 300W at the wall
my two year old laptop GTX 1070N does 750H/s per 150W at the wall (total paid for the laptop 2 years ago $1600 total ... Tornado F5) It is a whole freakin' laptop FFS
my rig with 3x GTX 1060 does 1050h/s at 380W at the wall (total paid for the whole rig $1000)

Do you get where i am pointing at?
Release an update for the Antminer B3 that improves the hashrate to levels that outperform the GPUs per Watt or release a 100% refund to all the B3 purchasers.

I am highly disappointed and lost all my trusty in Bitmain with the release of this B3 miner that is for AI research, developed specifically for Bytom costs so much and in the end beaten by a 2 year old laptop that costed the same 2 years ago, and is 2 times more effective per watt than the Antminer B3.

Dear Deathwingbg,

Thank you for your valuable feedback. Our engineers are aware of this development and they are currently looking into it.

We hope that you can understand that Bitmain builds and sells ASIC miners to cater to the market needs. As stated on our website, the hashing power of B3 after the firmware update is currently 1000 H/S, and we did deliver what was promised to our customers. We hope our customers understand that ours is a very dynamic industry and we do not control all the developments. Bitmain will continue to improve on our product technology and stay ahead of the competition.

Based on a number of other forums, we are finding that the GPU mining is not uniformly stable. Some have more success than others.

If you have not already upgraded to the latest B3 firmware we recommend that you do so: https://shop.bitmain.com/support.htm?pid=00720180519161243572MB78lOGz067A

As suggested by the article, https://www.crypto-coinz.net/bitmain-b3-miner-cracked-and-ported-for-nvidia-gpus-strike-back/ the GPU is running based on our software for B3.

Please do not hesitate to contact us should you have any additional questions. We thank you for your business and wish you a great day ahead.

Best regards,
Valerie

Dear Valerie,

So you (Bitmain) are well aware for almost a month that:
3 x GTX 1050 that cost ~500$ will produce 900 H/s and use only 210 W.
Compared to the BITMAIN B3 ASIC 760 H/s for 360 W for ~1500$

Do something about it! Fill your boots or issue refunds to all those scammed customers of yours out there.


I would assume that for someone with 5+ years of experience in crypto ASIC hardware you are well aware that ASIC should be way more effective at a certain Crypto algorithm than the GPU hardware.
You develop an ASIC for a specific new algorithm and do not test the performance against a 2 year old technology for GPUs ?  ?  ?  ?
Then you offer it to your customers making promises you cannot fulfill !
https://en.wikipedia.org/wiki/Application-specific_integrated_circuit 
ASIC is supposed to be way more effective then General Hardware


You could have stick 4x GTX 1050 chips on a board instead of the 12 x chips in the Antminer B3. and sold it that way... for better results.


DO SOMETHING ABOUT IT OR GIVE ME MY MONEY BACK !!!

Disappointingly yours,
Pavel Parushev

Dear Deathwingbg,

At the time that we released the B3 it was the most powerful option for mining Bytom. Some individuals exploited out open source code and successfully adapted it for GPU mining. While we support open source, it does leave our technology open to exploitation.

While some miners are experiencing a competitve hash rate with GPU mining, it is not clear if GPU mining provides the same stability that ASIC mining provides.

As we explained earlier, this is a dynamic industry where technology moves quickly and products might be overtaken by new developments. We released our B3 miners in good faith and provided accurate specifications as to performance. We do not plan to compensate against developments that took place outside our company.


Please do not hesitate to contact us should you have any additional questions. We thank you for your business and wish you a great day ahead.

Best regards,
Valerie

Hello Valerie,

I understand it is a very dynamic industry and a new bigger better ASIC may come any other day (happens all the time for the past 5 years)... i am watching the "revolution".
I also understand that those headlines that the algorithm was hacked are just for the buzz. As you said it is an open algorithm.

However the one thing i do not understand is how Bitmain placed 12 (supposedly expensive) chips in a box (supposedly ASIC) without researching the algorithm possibilities and being soundly beaten by a General Purpose Hardware such as GPUs (that you can use to mine 1600+ crypto algorithms, play games, play 8K video, crack passwords, etc.).

Two independent "Hackers" (Developers) were able to introduce GPU miners for Bytom. None of the Bitmain development team was able to do that in the past several months or at least research the possibility behind it. As a Business Analyst i think this is the very first step to do when offering a so called ASIC to the market for a completely new algorithm.
You and the creators of Bytom created the market need for Bytom miners... You worked together with them on the algo and then you say some lame "hackers" hacked the algo and made it more profitable to mine on GPU. Come on you must be joking.

I have been mining bytom with GPU for the past 3 weeks ... on the two different bytom miners ... and i assure you ... the Antminer A3 is the most unstable between the 3
( Accepted Shares 1000 ... Rejected 20 000 !!!!)
And my hash rate has never been more than 980h/s even after the upgrade.

So that makes me wonder what makes those 12 chips that were specifically developed for mining Bytom so expensive if they are beaten by 3 inexpensive graphics cards (chips) that are almost 2 years old.

If you make/produce Application Specific Hardware (ASIC) you first make sure it is better (more cost and power effective) than the General Hardware (GPU) and even then the Field-Programmable Gate Array (FPGA). It is not serious for the world leader in ASIC production to claim that the algorithm they worked in co-operation with the creators of this very algorithm (Bytom) and soundly promising they are the only one to offer Mining hardware on this complicated AI algorithm. To be beaten in less then a month by some "Hackers" that simply ported the algorithm to a GPU.

It is like boasting you offer a super expensive super computer, with great CPU and GPU power that you can use specifically only for AI research, selling it to the people (how did you call it to the market demand YOU created) and then being outperformed by a 2 year old Laptop that costed less 2 years ago... now costs half of what you ask for that supercomputer. Sounds like a joke right?

I also never mentioned that when we received the Antminer B3 for the first time ... it felt like an incomplete product... no FAN control (auto or manual) a lot of rejected shares... this never changed. You know the percentage of Accepted shares is something like 10% ... Rejected 90% and you are talking about stability? For my GPUs it is something like 95% accepted 5% rejected.

Not very kind Regards,
Pavel Parushev

Enjoy reading ...
B3 is total scam.

I feel somewhat cheated with this Antminer B3 brick[/left]

My almost two year old laptop GTX 1070 is making 750 H/s at 115W ... for a week now.
3x 1060 3gb in a not so optimized rig make 1000+ H/s at 360W for less than half of what i paid for the Antminer B3 (1060 can achieve 500+ H/s)
I expected more from Bitmain...
