Interested in sharing your opinion on changing the algorithms to be truly asic-resistant and considering to invalidate the Bitmain Antminer Z9?

How are u able to do research when the miner is not even delivered yet?

What sorcery is this?

He just need you to buy from his link in order for him to make cash !!

I was the one that had the info about ZEC miner from BITMAIN ....
They are coming more ASICS.  ;D ;D ;D infos later ..

This is exactly why they are calling this version the mini. Its a marketing and profit ploy. ZCash and Zencash are already not forking, so they will be able to sell a lot of these ASICs. Zencash was so kind to even retweet bitmains release tweet. Probably getting paid from bitmain too.

I was never a negative guy and always support GPU mining. But this is bad guys its the begining of the end for GPU mining again. Equihash has alot of hashrate and if it becomes unprofitable with gpus the rest of the coins will take a massive dive too :(

Vosk, one point I'd like to see you mention is that the ASICs coming out now separate the haves from have-nots.  Its impossible to get GPUs at retail price, and the people who can, have inside connections.  I don't think its a surprise that Bitmain is suddenly releasing all of these ASICs now that gpus are scarce and expensive.  At least these antminers allow anyone to get involved in mining, not just people who happened to be lucky enough to buy mass amounts of GPUs when they were 300 bucks each.  Lets also not forget about the lack of innovation from Nvidia and AMD.  AMD gpus underperform and cost too much.  Nvidia refuses to even release new models because there are no competition. The 10 series is 2 years old.  Kind of ridiculous that people insist on using old technology in the name of decentralization.

I guess it depends on were you live i just bought a 570 AMD 4gb for 309 after rebate paid 329 on sell and i don't have any inside connections new egg has a few selling for 339$ or more  570 and 580....


my bad 8gb

mine had a 20 $ rebate and it was on sell . .

Link???   :o :o ;D ;D ;D

At least in the states gpu’s are readily available now and most nearing normal retail values in many cases. I’ve seen stick in almost every store and every website as of late.

Unfortunately that price is still a fair bit above MSRP.... 18 months ago we were able to buy Rx 470s for as low as $170 each although usually they were closer to $200 at the time.

Sound like too good to be true, but that would be happening. Does anyone have an idea why Bitmain can do that?  ???

With that spec and prices, that's really hurting GPU miners. But, whatever it is, as GPU miners, we need to face the fact, keep going and focus on what we have full control over it.  ;)

Link for what ? for inside infos ? lol wake up !

Cant stop evolution. ASIC are made for mining. More companies just need to get involved to make the products affordable. GPUs are crap to use for mining. Im constantly RMA'ing cards in large amounts. They ALWAYS break. Sucks if you have a big operation. What are people going to do. Fork every time a new ASIC comes out? This fight against them is unrealistic and petty. Companies need to embrace the tech, and solidify networks with better machines. The most vocal are the smaller miners. Sorry....People with money will run the industry. Dont hate a computer because a monopolizing company. When you can buy asics for the price/availability of GPUs, EVERYONE will use them. Anyone who is serious about mining will switch. Anyone who says they wont, are full of crap. GPUs need to be replaced. Texas Instruments are pioneers in this industry.

More companies seems to make things worse. More choice yes, but a lot more hashrate and each company has to guess how many units each other one is making, so any estimate they make for customer profits and ROI are unreliable.

makes sense for zencash not forking, devs owned a lot of coins that they can have supernodes and continue profiting and a partnership with ASIC manufacturers might bring in the $$

What GPUs do you have a lot of trouble with and what’s their average temp / fan speed

ZEC is looking into it, they might fork after all, doubt it, but it's still possible.

i think its useless to fork, we fork now and bitmain just solves it again but the nxt time they break the algorithm they can decide not to sell.  actually even with this z9 mini, if they decided not to sell would we know that there is an asic already for equihash, at 2k usd retail price lets see 80m usd and they can control zcash network hash already, bitmain made more than 1b last year so they didnt really need to sell this asic, they can just write off 80m usd this year and not sell 40k units which they can easily do(2kusd/unit x 40k units is only 80m thats peanuts for bitmain) and with that they would be at zcash total hashrate already, if you guys were looking at hashrate of zcash, 3weeks ago it was only around 400, today at this time its 500 so means bitmain has already made the asics and probably mining it already well they got 2weeks to do it before they ship

so lets go to scenario where we fork, so probably hash goes back down to 400, they just make a new asic and this time they decide not to sell and just keep quiet well they can just do the 51% attack and screw us all, im a gpu miner but looking at how things have turned out maybe we can adjust the code so that a pool or miner doesnt go above a certain hashrate if this is possible since our only concern is centralization but it already is a fact we cant run away from asic they solved scrypt, ethash, cryptonight, equihash most at start saying its memory heavy so no asic can mine it but now asics are here and with the recent 51% attacks actually looking at btc ltc dash these are the coins with asic but cant be attacked cause of very high net hash and there isnt enough power on nicehash to attack them, issue with decentralization i think isnt with asic, its people selling to nicehash that is the issue cause recent attacks already proved this

so you know i didnt buy the z9 mini which i am actually having second doubt why i didnt, change algo bitmain solves it again and they can decide not to sell so we all end up as losers, if its possible to include for example a limit a worker to a certain limit on hash and maybe even pools then maybe this solves the issue, max hash a worker can have on network 10k sols i dont know if this is even possible but running from asics is not sustainable anymore if bitmain sells a new asic i will probably have to buy 1 already, also an issue with centralization i think even if its gpu only we already have that issue, how does it feel since aug last year until now i dont see any vega cards here but see 1 guy post getting 500vega gpu last nov

so, lets say they fork in x16(r or s) how much it will take to make an asic that is profitable ? :)

We just need to change the PoW algorithm every 6 months. The ASIC company cannot make ASIC and profit in such short period.

PowerColor and ASUS varieties for the most part. Temperature isnt an issue. The rigs run in ice cold data centers. They just arent made for this constant use. 100% usage constant just kills it after a while. Normal use for a card is erratic.

ASICS wouldn't ever beat a GPU. Once they are not profitable anymore, they dont have any apparent use (doorstopper, heater yes...)
They are not versatile, can they be programmed to mine other algos than stated?
Stated the above, they dont have resell value, while GPUs will.
Finally, there are many more profitable algos/coins for GPUs than Equihash, so not a big concern.

I got a message from bitmain my Z9 just shipped.  I am 90% GPU but just needed to see this thing.

I setup my z9 on MPH's switching port 17023 yesterday and it was working fine, but when I woke up the miner had spun up and down a few times mining on a backup pool for moments at a time earning nothing basically. I was going to mine on the single coin 20XXX ports but it was giving me problems, which is why I switched over. Well seems the ZEN pool is down and the switcher thinks it needs more hashrate causing everyong to stall.

I have as of now changed to the ZCL port, and it seems to be working just fine.

How could you order and got delivered?
When first delivery is - Shipping: August 24th- Sep.4th ?

Where there a first batch, and it is only 2nd batch left?

Yeah i guess so the first batch cost 2500$ or? and the new one like 875$

zencash in mineable with asic z9 mini yet? !! ???

gulyas


I am going to order a Batch#2 Z9 unit tomorrow. I am excited to see how good the return actually is in the real world. Gulyas, it is a bit disturbing to see that you were having issues on the ZenCash Pool. Any further comments on that? I have 49 RX570's, 1 RX580, and 1 Vega56, and I am tired of giving so much $$$$ to the power company. I am running some S9's and Giant B's right now and like them alot. They stand up to the heat better and are easier to ventilate. I am seriously considering selling all of my GPU's. Just not enough hash/watt imo. I want to run 19 of the Z9 Mini units and start buying the Innosilicon A9's. After a bit of math, I could conservatively make +/- $1000 per day and still use 3000 watts less than the GPU's are sucking down.

I agree with NetfetMiningCompany when they said "Cant stop evolution. ASIC are made for mining. More companies just need to get involved to make the products affordable".

The gamers can have their cards back, I can give less $ per hash to my power company, have a system that is easier to vent, have an easier build plan for scaling, etc... We have real mining hardware built for a specific purpose that is finally starting to become affordable. We should use it.

I don't want to keep all my eggs in one basket either. I plan to use the Z9 profit to buy the A9's but I might get ASICminer Standard 48TH (https://asicminer.co/shop/asicminer-standard) also just to have more than one algo. Ideally I would like to have 5 or 6 algos. Maybe even some E3's or A10's for eth as well if they don't go POS too soon. When they do go POS I am done with ETH entirely.  Check out https://www.asicminervalue.com/. Has a lot of good info for research on ASIC units.

I believe that with so many companies making asic units, there will always be one around the corner that will fit a persons needs regardless of forks or what other rubbish is attempted to prevent real mining. If I had it all to do over again, I would never have bought any GPU's, only asics. I was a n0.ob then and didn't know anything. Luckily as Maximan pointed out, the GPUs have a resale value and I am going to package them with a riser card and sell them. At least that way I won't feel so much like I wasted all the $$$ that I spent on GPUs. All I will have really lost is profit and time. I have learned a lot though and GPU mining was good for the experience. I would totally suggest if one is new to mining, to start with 1 or 6 GPU's to get a good feel for the software, pool setup, and operation.

One last thought is that if we as miners did graduate to mining specific equipment more rapidly, we could have enough hash power to set up more pools and offer additional decentralization. Best case, I make enough to lease a building for mining hardware and do set up my own pool eventually. Worst case I am flat broke and have several doorstops as Maximan again pointed out. They will be damn nice doorstops though, and it will have been an amazing ride.

Thanks and Happy Mining!

Can always open up a video arcade instead of selling them. I was thinking of making a VR arcade as the headsets are reasonably priced now.

It will not be mineable in the near future.
