Bytom Mining - ASIC algorithm now cracked by GPU miners? Big profits?

[exsexs]

When are payments received in f2pool? I've been mining for 3 days and I have not received anything yet. Is it necessary to register? I have registered but I can not associate my account with the mining of bytom

50 btm minimum payout

WTF? How can I change it?

you can't

[cost82el]

if you stop mining and if you dont reach minimum payout you can submit a ticket to get paid.

Switch to another pool such as UUpool or beePool(sp) that has lower minimum payout threshold (1 BTM).

[VoskCoin]

For the first time an example of how a GPU miner destroyed the profitability of an ASIC.

Uupool: 6.44331024 BTM per Khash/s   

The ROI of B3  is near to 2 years.  

ironic isn't it?

[LMN0PY]

B3 at current profitability is 7.5 months though?

The fact that they easily upgraded the B3 from 780 - 1050 in a week shows they seriously handicapped these miners (on purpose or by design, who knows). They still run quite cool with minimal power draw - thus beggin the question how much were they limited?
Would be interesting to see someone "hack" one... I bet doubling is not a far stretch, with slightly more power draw. They are capable of so much more.

It's foolish to think that general purpose hardware would trump ASIC., pure nonsense logically speaking lol.

[thedreamer]

UUPOOL is not counting a ton of hash rates, just FYI.
They're probably using the 50%+  for their own pockets.

[Rabinovitch]

Meanwhile... v3.0 is available. https://github.com/NebuTech/BTMiner_NebuTech/releases

1070 is hashing at up to 540 H/s (single card in PCI-e x16 slot). On risers it's about 490 H/s. Win7.

I see my 75 BTM in "unpaids". When will I receive it?

Yeah, look at this Bitmain's .50 cent army.
B3 are door stoppers. 2*1060 gives more hash while consuming less power. If these devices could be upgraded, Bitmain will only do so when they have mined enough with their bigger ASICs. Then you can pick some meat from the leftover bones.

[monkins1010]

Ive been looking at the hash rate of the v2 windows miner and over ten hours of hashing i got average 847h/s hash rate on antpool, and the devfee has hashed an average of 246h/s .

so my maths say its a 29% DEV fee on the v2 windows miner.

[foxgiggle]

Not bad: 1x1070 in PCIEx16 slot and  4x1060's  in 1x risers give ca 2 KH.  With 730W power consumption and about the same price it turns my B3 pseudo-ASIC into a doorstopper.

# BTM GPU Mining Software (NebuTech BTMiner)

BTM (better than the original chain) mining software for Nvidia graphics cards.

## download link

[Download from here] (https://github.com/NebuTech/BTMiner_NebuTech/releases)

## Features:

* Supports Windows, Linux (Tested on Ubuntu 16.04)
* **Windows GUI operation**
* Mine pools supporting the standard stratum protocol, tested: [f2pool] (https://www.f2pool.com/), [antpool] (https://www.antpool.com/), [btcc] (https: //pool.btcc.com/)
* Almost no CPU and PCI-E bandwidth, available for existing 6 or 8 card mining machines
* Optional CPU-accelerated mode to further increase the computing power on machines with high-end CPU and high PCIE bandwidth

## Instructions:

1. **Updated to the latest version of the Nvidia graphics driver. Older drivers are not supported. (Driver version needs to be greater than or equal to 396)**
2. ** Double-click on `GUI_Wrapper.exe` to open the Windows GUI and start mining. **
2. Use Notepad to open the `Windows.bat` file (Linux system changes `Linux.sh`), modify the pool address after `-url` and the wallet address or user name after `-user`. If you have a password, add the `-p` parameter and password.
3. Double-click on Windows.bat to start mining. Linux starts mining on the command line with `Linux.sh`.

-i parameter have been remove , but now power limit % have a lot less impact power consumption .

now it say 3% fee , yesterday on V2 i observed change in fee they occurred more often but during a significant shorter time.

Yeps, B3 at 50 degrees and only this frequency. At first it was 780h for 360watts. We need new firmware to increase the frequency. The previous firmware increase watts by 20-25 and gave 280 more hash. Miners currently cant control the frequency. No known hacks. Hopefully a stronger firmware gets released soon....
20 more watts for 300 more hash I hope.

Any good pools for Bytom?
uupool is not counting like 50-60% of the stable hash rate sent to it.

f2pool is good for me but i stop mining on f2pool becouse 50min payout
back to uupool

uu is fine for me, maybe check ur ping to the pool

[jamuraan]

I have setup my miner to mine on any of the btom pools. I keep getting "The remote host closed the connection" and also I am not getting any Accepted shares. It keeps saying New job arrived and Found a target, submitted.

Is the profitability very high or am I doing something wrong?

How much memory in your system?  I had 4GB and ran into this same issue with 25%-50% shares being rejected by pool.  However, when I tried again with 8GB RAM then it became stable and normal with very few rejected shares.  My cpu was C3930 Kaby Lake edition so lower end cpu too.

[Sikkan666]

I have 4 rigs.. ranging from 2 GB RAM to 4 GB RAM.. cant say I experience any discarded shares on any of my rigs.

oh and by the way...this algo really likes power... normally my cards use 1300w(lyra2z) to around 1500w(equi or/and eth) but this shit wants 1800w.. prolly because every CPU have to work more aswell

I guess they are releasing more efficient miners in the future!

If you want to reduce your power consumption try this:

1. Install Nvidia inspector 》 choose force p2 mode in common off.  Also choose maximum performance.

2. In afterburner. Set power limit to 55%. Then on each card set core to +150. Ram +400.  (These should work on any card. With Samsung you should go to +500ram.) Going higher ram has no effect. Higher core can help. Try steps of +10.

3. Goto power settings. Advanced in Windows and change maximum cpu usage to 10%. This will shave off about 20watts per cpu and only effect the hash rate slightly.

On a i5 4 x 1060 this gives you about 1080h/s. At about 300watts.
