Bitcoin Forum

So I just got an email from Halong Mining and for some reason I do not feel good about it  :-\

its going for USD 10,499  ::)

What do you think?  ;D

-----------------------------
The email:

Perhaps when you reach your hands the daily per day will be around $ 200, and if you ship a lot, it will be around $ 100.
ROI seems to be fast, I think that it is shopping with high gambling. :D :D :D

It may be a good idea to dispose of giant b and purchase one. ;) ;) ;)

Na i dont think its a good idea .. the price is over rated and i personally believe that it should not exceed the USD3,000. I think I will wait for the Obelisk I can purchase 3 units with price of one  ;D

$10,500?!?  >:(  Think I will sit this one out.   There are too many variables that can derail this miners roi.

a. Bitmain could come out with the "DC3" (1.2th @ $2,300) to smash down profits
b. Obelisk's Decred miner early release
c. Halong # of units they will sell is unknown.  If they sell just 3,000 units, then the Decred network hashrate will be quadrupled (and daily/profit cut in fourth).

Mark this post,,, Decred network hash rate has recently been peaked out around 1,500Th/s.       https://dcrstats.com/pow

Good luck to all buyers at this price point.

putting the price point aside

I am really wondering about the legitimacy of the company  ::)

I have been looking around and for some reason I cant find a single review from any user about any of their miners (which I find that very disturbing)  :o :o

Yeah, god knows I tried with them but they were not interested selling a miner for me to review.
This was back in January or so.

really, Newbie with 3 activity. Thiis looks like self promoting to me.

Oh, no worries there. Halong's method of 'self-promotion', if you can call it that,,,, is to give everyone the silent treatment to piss people off. ;D

Ouch that is harsh

i just said that the company does not look legitimate lol on which planet this sounds like self promoting?  8)

anyway just to make you happy

I would rather wait for Bitmain to come up with DCR miner than risking my $ with a company without any track record  :P

they recently elaborated about this particular issue with T16 units for a demo purpose before start of sales https://halongmining.com/blog/2018/03/07/dragonmint-btc-miner-uses-version-rolling-asicboost/

This could be a good miner the company could end up being a good company.

The coin  is too small  the total hash rate is too low.

a 2.1th miner using 1300or 1400 watts for a 1420 th network = disaster.


to give a proper scale

the hash for btc is

26,070,479,913 gh  so if someone sold a btc miner using 1300 watts it would mine at 37,243,542gh


or 0.0000349 watts a gh

so this miner will kill the network.

The only robust network  besides btc/sha 256 is ltc/scyprt

Agree!

Wasn't it listed at like 5599 a day or two ago?  They doubled in price that quickly?

Think i'd rather buy 10 A3's at that point (yes sucky power usage but ...damn)

I believe that is a different miner offered by them.  I could be wrong but either way i wonder how many of these they are producing, anyone have any solid numbers.  Even if they dont sell out they will just hook them up themselves.  Hopefully though they can compete with bitmain, need another solid asic player in this market

Awh you are right. These are for Decred.

Based on current price/difficulty that would bring in 335 a day before power.  Pretty crazy but we all know how that goes after a few of them hit the market.

It is always healthy for consumers when companies compete with each other hence its good to have a Bitmain competitor to come in. They will fight and we will have options  ;D ;D
I hope Halon becomes more transparent and give few units out for reviewing (AT LEAST), I just checked the website and they have a Sia miner and the it can mine 2.3 million Sia coin per month  at 1250 Watt :o :o :o

There's two different Blake256 miners they offer, the cheaper $5000 one is faster in terms of hashrate but uses more power and is less efficient, whilst the more expensive model at $10K hashes at just 2THs but is more efficient. At current rates the cheaper one makes more, but don't count on anything. This is a D3/A3 situation ready to happen.

What? B29 and B52 are different algorithms, Blake256 and Blake2b, for different coins, Decred and Sia

I bought 4 of the b29s 😁

Best of luck my friend

please share your reviews on them once you get them

42k! now lets see how Decred diff will rise...

I was just checking the Top miners on Siamining.com and guess what
Have a look at this
https://siamining.com/addresses/25865daf640696361b432bd517b812270d8459af48f13876108354ee7e028e0e15c13ab5030c

This dude is mining at 1,941 TH/s  :o

and his single worker hashrate is (Average) 4000GH/s

and I just rechecked Halong website and the Black 2B hashrate is  3.83TH/s

and according to his payouts he started mining on 15th Feb 2018

I dont know what to think now :o

It looks like halongmining testing the miners before they ship. Either that or they are trying to make more profits since they obviously have the miners ready to ship so people will be getting used miners...

Looks like a rolling test of the new blake2b miner ($5549) and looks like most mine around 4th on Siamining.  Still must be a kamikaze to purchase and hope for ROI with so much hardware hitting the network and SiaCoin price around $0.014. 

You guys are confusing the miners. One mines decred and one mines Sia. The decred miner would make $300 a day. The Sia miner makes about $100/day but I feel like that will go down real fast. Decred miner has best potential for ROI

That can not easily be known.  You need to know how many of these are coming out in the first batch to know.  You cant use calculators now to see what you will be getting when the miners start rolling out.  Its all speculation until it happens.

I agree but all the inline calculators are pretty accurate for my bitcoin, Litecoin, and Sia miners. I know it won’t be that way for long after released but it will be close for a little while.

My decred miner should be coming by the end of the month / first week of April.

Not sure why everyone is so negative about these things. I make a lot of money on my ASICs...Much more than I did with GPUs.

Yes they have 3 miners
and I was referring to the Sia miner not the Decred miner

I am still disturbed by these guys  ::) ::)

Either they are really a scam or they suck in marketing

this is a tweet by a guy who claims that he got his unit from Halong and guess what??!!!!  this guy just created his Twitter account few days ago  :o :o

And they also had a tutorial video on how to operate the miner

all I saw in the video was an ANTMINER ASIC and a HTML web interface of Halong  ;D ;D (PROVES NOTHING)

GOSSSSSSH!!!

We will find out for sure this week. The miners do exist because you can see them mining on the pools but the real question is when or if they will actually ship to customers. They were suppose to start shipping this week has anyone gotten shipping confirmation or tracking?

Could finally put to bed the whole "Dragonmint is a scam" debate... wonder if I could use Augur to bet on it 😉

Not until we see a good video review  ::)

Hi, we've received many at our Colo (minery.tech) and at Luxor (mining.luxor.tech) we have plenty of hashrate from B29s. Can confirm they are not a scam!

https://i.imgur.com/KjES15f.jpg

Got my units yesterday! Hashing around 10% above advertised spec too. 6 units pulling 21.5 amps on 240v.

Happy customer :)

Did they send you tracking for your miners? I still haven't received any tracking but their support said all the miners have been shipped and they are waiting to get the shipment manifest before they can update order status on their website.

DHL sent me a preship advisory right under 24 hours before Halong's email. I ordered within minutes of these going active too, order #552x. So if they all shipped today, I'd expect a tracking as soon Halong updates the orders.

What are they currently hashing at for you and how much of a power draw per unit?

21.5 amp pull on all 6 @ 240v is about 860 watts each
GUI shows between 2.31-2.36T, will report on pool average hashrate after a few days, seems to be a bit lower at the pool

i ordered 2 decred miners on obelisk.tech (first batch) , with for both miners a 1500 ghs/s , but i am scared a little now that when they arrive they mine peanuts and crumbs they have to comete with bitmain and halong now

I got am email from DHL that my b29 has been shipped.  My issue is where do I find a pool to mine decred?  More specifically I have setup D3s, and S9s but that was following specific directions for asics to mine on asic pools.   Is there am asic pool out there for decred?

You can go to Luxor pool. What was your order number? I'm number 6600 and dieing to know when mine will be shipped!

Yes I can see alot of unboxing pics and videos and we can say that they are as real as it gets.... one thing I do not understand is why they adopted such a bad marketing strategy that made people believe that they are a scam...


For DCR Pool you can try https://dcr.suprnova.cc/

I finally got tracking for my miner today so hopefully it won't be too long before it arrives.

I got a tracking number today

Anyone know how long after getting a tracking number the miner arrived at their door? I'm just hoping its not going to be another week.

it is dhl express

so  go to dhl  and sign up for notifications as the item is expensive you may need to pay some duty on it.

should be under 1 week

After testing a few pools, I like coinmine the most.

Picture!

Here's the rest of the GUI for Halong's B29 units -  I uploaded to an imgur album: https://imgur.com/a/LjgWH


Color change! I like the black background more.

My setup for the 6 B29's -- not the cleanest i've had, but it works!

https://i.imgur.com/b9URvcI.jpg
https://i.imgur.com/1irPW6g.jpg

On another note, I hit 6 blocks already. Should of been solo mining with that luck :)

Damn its got a real nice GUI and has some cool settings. I really like it will auto-tune out of the box but is there any settings for manually overclocking? I wonder if we can do some tweaking from command-line like putty.

Unfortunately not. You can't manually tune it at all. During calibration it appears to do 3 or 4 rounds of 10-12 minute peak testing, and it redirects to CK's pool during this.

1 of my units is at 2.31, another is at 2.33, the other 4 are 2.36

The on pool hashrate seems to be around spec, so there's some loss between GUI and actual pool hashrate. Perhaps this will be hammered out in a future update.

Sure, try Luxor you won't regret it!

Here is a setup guide:

Cheers!

Looks like luxor is reducing their fees to 1% for the next little bit (https://twitter.com/LuxorTechTeam/status/989474144239652865) - I'm going to give them a shot.

Does anyone know when they will go back in stock?

Innosilicon has the D9 available last i checked, cheaper, and same specs ;)

*coughsameminercough*

Halong B29 is back in stock as well, listed at $6600 (about $7k w PSU and shipping to US)...

Where is this for sale for 6600? Halong direct website only has one miner for sale that I can see and it is not the decred miner.

Weird, I wonder why that is... I got the email on the 27th and the link they gave was...
https://halongmining.com/shop/dragonmint-b29-blake256-miner/

I put it in my cart just to see total but wasn’t ready to pull the trigger for the price... They had the T1, B52,  and B29 all listed in the shop , but only the B29 showing in stock.

Now they only show the T2 bitcoin miner that’s not for sale yet, weird right?

I can attest to this. I saw it there with the price drop the other day. Coincidentally, it was made available after the batch 1 of Innosilicon's D9 miners were sold out. I have a D9 in route so I'm kinda glad to see these are no longer listed by Halong, at the moment anyway.

D9 = B29

Can you give an update on whether or not you still like coinmine the best after mining with them almost a month?

I was leaning towards coinmine over Luxor pool due to the higher fees but I read a comment that Coinmine wasn't computing their hashing power correctly or their coin payout wasn't adding up.

Curious to learn any other insight (pros/cons) you can provide from the mining pools you've tried and why you like Coinmine the most. Thanks in advance!!

Halong has put the T1 (BTC) back up on the site, and the T2 (BTC) showing as well (both Unavailable / Join Waitlist) , but still no sign of the B52 (sia) or B29 (decred)... hmm

As many have pointed out , INNOSILICON D9 (decred) and S11 (sia) (same specs as Halong, possible partners?) are showing stock avail to order now ...

yea i noticed that, however the price difference makes me not want to bite the bullet 6600usd vs 9070usd

Still on coinmine. Has the most consistent payouts.
None of the pools have completely accurate hashrate. It all seems a bit below spec at the pools, even though GUI shows otherwise.

Laying the units on the side helped temps a bit. Get to mining when you get them :)

Thanks for the feedback!!

Received my D9 today which has the DragonMint GUI and connected to Luxor. Noticed this worker name (looks like a wallet address) already received rewards prior. Do I need to change the worker name to my DCR wallet address?

Yeah, definitely do that right away, that how it was mining Sia ... I mine sia to Luxor mining pool , user is walletaddress (or walletaddress.001 if you have more than 1 (so you can do .001, .002, etc...) or you can just set your wallet address

Has anyone auto-tuned their B29? If so, is there any noticeable difference?

I'm asking for help. I ordered and paid for this ASIC in March and so far I have not been sent it.
HalongMiner promises to send ASIC, but always postpones it.

Waste of time and hash.

Mine is automatically doing auto-tune, is there a way to deactivate it?

On stock b29?

Yeah, actually it is a D9, but as model number and all, it is written B29 and the backend is DragonMint. I upgraded to the latest firmware, still it is constantly stuck on autotuning.

That's a firmware bug, it does nothing to your actual hashrate. I've got the same thing on my poorest performing b29, the update to the public d9 firmware runs visual autotune in a loop too.

Phew...btw, are you having fluctuations of the hashrate on the pool end as well...mine fluctuates from 3 TH/s to 0.9 TH/s?

This is standard fluctuation. Average is what counts - these all have appeared to hash a little below spec (1.9-2.0 avg) poolside.

Anyone know what the ideal ambient temp for the B29 is? I couldn’t find any info anywhere. On Inno, specs state 0-85 Celsius for internal. Looking at the UI, each board has 3 temps. One of my boards (middle) is reading 67 77 81. Should I start getting concerned?

Can someone also elaborate on how laying the miner on its side helps the temps? Does it matter which side to lay it on?

I've wondered about the temps also. For each of my ASIC miners that I get, I usually write a python script to monitor certain statistics of the miner so that if something goes out of range, I'm notified of it immediately. In doing this, I found that the three temperatures were labeled Average, Min, Max. My fan percentage fluctuates between 60% and 95% but it seems that the firmware attempts to keep the max temperature no more than 77 for me. Currently, at 75 max, it's pulling about 830W. I'm getting an average hash rate of 1.95 Th/S over the last two days on coinmine even though the firmware constantly reports 2.36 Th/S. I would have liked more control over the fan duty and the voltage configurations. FWIW, I did do the calibration when I first got it and left it Auto-tuned for a while, but now I have turned auto-tune off. I'm not sure I noticed a difference either way.

As for laying the miner on its side, I have not tried it. I have it sitting up-right.

Yeah my miner is about 1.8. Btw, saw your name on coinmine. Not bad, your in like top 5 or so.

They generally run cooler laying on the right side (exhaust facing away)

The temperatures represent lowest recorded, average, and highest recorded.

Have you kept it on balanced mode or performance mode? Even on balance mode, I am getting alot of HW errors though. In 11H of run time, I have 219 112 33 HW errors. Not sure if everyone is having the similar issue.

I have a Inno D9 so my firmware may be a little different. I don't have an option for performance or balance mode. However, after 47 hours of running, I have a total of 685 HW errors.

Thanks for the helpful info. Laying it on the side definitely lowered the temps. It seems like the temp readings may be for 24hr (??) intervals cus the highest recorded has definitely come down.

I've been mining DCR for a little over a week with my one miner.  So far I have found 3 blocks generating 39 coins towards the pool which is significantly less than my reward amount. Wonder if I would have found these blocks if I was solo mining or is it because of the consolidated hashing power of coinmine? I'm sure with your hashing power, you're finding blocks left and right. Would it be more profitable solo mining? Granted there are no guarantees if and when you'll find a block but seems probable if indeed your/my miner found the blocks without intervention from the pool.

Up until very recently, solo miners accounted for 2nd highest (31%) of the total distributed hashing power on https://dcrstats.com/pow. At the time of the snapshot (May 4th), Coinmine totaled 45.6%, Luxor at 13.7%. Those 3 groups accounted for 90% of the hashing power.  

Then f2pool came out of nowhere now making up for 29.7%. Coinmine accounts for 39.3%, Luxor with 12.3%, solo miners now only 2.1%. This totals up to 83.4%. f2pool is Chinese pool and has a very nice UI and the pages seem to translate to English okay.

I too hit like 8 blocks really quick when I got my original 6 DCR miners. It's all luck based, you could hit 3 blocks in a row, but the chances are astronomical. Pools are convenient to not have to worry about setting solo mining up. Over time it equalizes.

Glad to hear temps got better on the side! They definitely helped all of mine. I've looked at f2pool, and it appears to be 3% PPS. Might point some of mine that way to compare over time.

I'm investigating setting up solo mining with my ASIC. I've downloaded decrediton and sync'd the block chain. I also see that the dcrd process is running. I can't seem to find any help on anything else related to setting up solo mining. Can someone give me the jist or point me to a tutorial?

The thing that is most retarded is that Innosilicon is flooding the market with miners just like Bitmain and unlike Bitmain they only give us a 90 day warranty. They have now made it a 6 month ROI at least with more asics on the way and if you have a board take a shit you are screwed because they won't replace anything even though you paid $7,300.
