I don't think you'll get a mod speaking to him. Perhaps you could try it (or I, if you'd rather not)?

Just look at anyone who uses that quote in their own post where it's evident that they haven't looked at the actual post that was made by the original/first user.

Normally I don't post here  but that  type of false quote  is simply poor behavior on cuteman's behalf.
20143  Other / Meta / what does the following false quote do to this forum? on: May 09, 2018, 09:12:27 PM

this is a false quote:

the Dragonmint is supreme.
Sure, because they use 10nm chips produced by Samsung, while Bitmain uses 16nm chips.  

But I wonder why efficiency is so low -  16TH/s , comparing with Bitmain's 14Th?    10nm should have at least 60% performance over 16 mn, doesn't it?







real post below
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
That doesn't change that these are more efficient than the S9 so will give you more BTC for every $ you spend on electricity. That's the only thing that should matter.
You realize that the efficiency is so close that your arguement is null and void right?

At 10 cent power you are talking about a $5/month difference in power for similar hashrates and the Dragon costs literally twice as much to purchase new.

It would take the miner running 10 years for things to even out.


You need to look at the big picture and not at one small data point.



This term, "more than" is being used quite a bit about these miners, to justify it's shortcomings. To further the justification, the resident Bitmain Haters, ignore these shortcomings in a spiteful bliss. There's no changing their minds about it. 1 out of the 5 they ACTUALLY received, hashes near or slightly above spec, so it's instantaneously proven, to them, the Dragonmint is supreme. Nevermind the other 4, that have to be tinkered with, just to come close to the 1, with a efficiency loss. These consumers are oblivious, simply for the bragging rights of having this miner. <-------insert face palm here!!!

Is this scam or real?
https://asicminer.co/shop/asicminer-equihash
I saw it somebody post it on the zcash forums:
https://forum.z.cash/t/let-s-talk-about-asic-mining/27353/1906
At first glance it seemed like a scam to me, but a few people over there say it's for real, they have sha256 too.

only people that have zero understanding of the economics of mining will buy it.

most likely it is a losing guess if you buy it even if it is real.

It will be forked to death
20145  Bitcoin / Hardware / Re: DragonMint T1 16TH/S halongmining.com on: May 09, 2018, 05:56:35 PM
And unlike the Halong Dragonmints, miners from Bitmain, Canaan's Avalons, and the eBits will run on ANY sha256D pool you point them at.

that is the biggest knock against them.

and the question remains  why won't  more pools add it the software is not that hard.

I know the answer to that for most major pools.

5% dead gear  is common for bitmain.

so you got 20 good and 1 bad

A  rma will cost you $$  consider it part of the cost of doing business.

You could ask them for a good coupon  maybe they would give you a 300 to spend on a s9i

If you insist on performance   you will need a cooled room  70f or so and a bigger psu  like the delta 2400 watt or the hp 2450 watt.

Or do my settings  and get better results.

@ jstefanop  are all above addresses good?

I just sent 0.0022 from profile wallet

https://blockchain.info/tx/5680de333a1efaac0e660aab6030ceb5bcf141614d8bf65cd12a0769840e7bde

So 0.0042 btc total

 will be saving 12 x 100 = 1200 watts   that is over 850 k-watts a month. that is 85 dollars at 10 cents

I will send to you again in June.

20150  Alternate cryptocurrencies / Mining (Altcoins) / Re: who bought bitmain Z9 will face a big issues now on: May 09, 2018, 04:40:46 AM
Also tell me how you can brick a GPU with a fork.

power up the GPU and start mining. While mining, drag your fork across the exposed pins/leads of components on the board, soon all the magic smoke is released, et voila, GPU==brick.



Thanks for the laugh
20151  Alternate cryptocurrencies / Mining (Altcoins) / Re: ASIC mining reasons Destroying future value of ZCash (ZEC) ? on: May 09, 2018, 03:45:31 AM
I was very disappointed when I heard that release a miner for the extraction of ZEC. It will be very good if the ZEC team changes the algorithm to support miners on GPU and altcoin decentralization.

Don't know if you guys just haven't read the news but, Zcash devs have made it clear that they will make Zec's ASIC resistance an "immediate technical priority." Wait till the news hits the fan. ZEC value will probably rise in the coming days. Could be a good opportunity to buy some today.

My source: https://www.ccn.com/zcash-foundation-to-make-asic-resistance-immediate-technical-priority/

Did I get to say told you so to those that spent hard cash on the z9

20152  Alternate cryptocurrencies / Mining (Altcoins) / Re: who bought bitmain Z9 will face a big issues now on: May 08, 2018, 11:47:23 PM
zcash is laying a trap to fuck all those asic buyers hard once gear hits network that will commit with this announcement


we wanted to fuck asic buyers hard so screw off you piece of shit asic miners.  We lied on purpose to suck in morons to buy asics that we bricked .   We don't need your stinking asics Cool


Now between you and me I doubt this happens but there is zero liability from bitmain if it happens.
20153  Bitcoin / Pools / Re: [145+PH] KanoPool kano.is 7 BTC giveaway 🐈 US,UK,JP,NYA,DE,SG on: May 08, 2018, 11:39:17 PM
I don't think Bitmain is hurting for money, but I could be wrong.  More people than not say they mine with the hardware and release it to the public once they kill the rate and make money off of them.  I wonder if they do mine on all the machines if there profit is based on the coins they mined or is the 3-4 billion in profit from straight sales? 

 This article from cointelegraph.com (maybe reliable, maybe not) says
"the four-year-old Bitmain reportedly made between $3 and $4 billion in operating profit in 2017, whereas Nvidia, founded 24 years ago, made about $3 billion during the same period. "




they were holding 30000 btc in dec 2016  1000 and in dec 2017 coins were 19950 plus add 30000 bch worth 2000

so 30000 x 1000 = 30,000,000 became 30,000 x 22,000 = 660,000,000  that is a 630,000,000 profit

of a traceable set of accounts they have.
20154  Alternate cryptocurrencies / Mining (Altcoins) / Re: ASIC mining reasons Destroying future value of ZCash (ZEC) ? on: May 08, 2018, 11:19:34 PM
Whats wrong with a ZEC asic?

10k sols = about 24 GTX 1070s at stock settings.

24 GTX 1070s at stock settings use ~3600 watts + 100w for the rest of the machine.

ZEC asic = 300 watts.

So you need $10,000 worth of parts to make the same hashrate and you burn 12x the power.

This will be a nice quiet machine you can run in any home off any cheapo ATX power supply.

This is a win/win for anyone wanting to mine equihash without breaking the bank.

You can also take this misinformed idea that ASICs promote centralization when that is so not the case. This machine makes it easy for anyone to get into mining without the complications of multiple unreliable GPU rigs.


the bold is wrong  my equihash has 99% uptime with gpu's my gpu gear has 3 year warranty from real companies like evga msi intel corsair. my gpu's have resale value.

and they still earn money on equihash.



one more thing

 buy that asic and have then zcash/dev change algo on July 1 with the simple statement we wanted to fuck asic buyers hard so screw off you piece of shit asic miners.  We lied on purpose to suck in morons to buy asics that we bricked .   We don't need your stinking asics Cool


Now between you and me I doubt this happens but there is zero liability from bitmain if it happens.


So do you feel lucky?
20155  Bitcoin / Pools / Re: [20 PH] ckpool.org ZERO FEE SPLNS no registration mining pool on: May 08, 2018, 11:00:53 PM
If you're in a deferred position when a block is found, the HERP is added to the next round - and it can effectively double the herp by doing so. If you are in the top 100 with the added herp the next time around you're guaranteed to get paid. If not, you will be in the interleaved group.

All of this shows you are much better off sticking to the one address. You'll get paid more regularly and are more likely to get the full payout with each block find. Additionally it means other miners get a look in sooner so it is nice manners to do so.

Makes perfect sense.  Thanks for explaining.


Yeah I have two addresses. I will not add a third and I will let the 1Jd address die.

Received 5 units today via DHL, order number 19xx, southeastern US via DHL.

The Good:
Units were packed in Bubble-wrap bags and foam carriers, individually boxed.  No clunking noises.
I ordered for April delivery, and am ecstatic to see them.  For context, my previous miners were Avalon Batch 1's (Months late) and Black Arrow (Never received anything).

The Bad:
They did not include power supplies.

I'm going to see if I can scratch up a power supply so I can test it.  It looks like I need a regulated 12v 1500 watt power supply with /10/ 6 pin molex/pci express connectors.  I'm open to suggestions on units known to work.

(My old name here was FarmerGreene.  That account has been deactivated and I cannot recover it.)

if you are usa based and have 240 volt power   here are some I tested

Then Donate now and jstefanop will, he did with the Alchemist miner and charged a one time fee .. it was reason able and this should be even lower because all he has to do is write the code . i wonder what he can get out of these miners this far down the road hash wise .

IN fact i donated the other day when i saw jstefanopis writing something for the L3's i know hell do it right . ......

...

I just donated 0.003 btc to his address

https://blockchain.info/address/14w9Lea6kdVzspJk8TQRe7qSYu9LhzJJsh

https://blockchain.info/tx/9401c0ee31116b421b1e6204bbadba2f576e39ad72f0d10a9f1eade9efdffb3c

I also purchased 8 of his usb sticks last winter.



Thanks to the very few of you that have donated. Id spend some time to write a GUI version, except I would need to create a custom firmware version from scratch, since there is no way to edit the web GUI without updating the whole bitmain firmware. Figured this way would be easier and not require you to update the firmware at all.

 I know the command line seems scary to some but this is super easy to do, and there is very little risk of screwing up your antminer, even if you accidentally delete the whole root directory :p Bitmain's firmware is pretty good in that regard since they unpack the whole kernel and stock filesystem on each reboot.
