Can't hurt to try and see if they're legit. If they're new to the mining scene they might just be inexperienced with everything, but lower sound could still be a small plus, even if it's not a huge bump up in sales. I do find it a little strange they aren't willing to distribute any units for review, though. Even one Hotmine gave out a few units of their Bitfury miner for review, and we all know how elusive those things are.

Syan's looking doubtful but I'm glad you made an effort to see if the miner is real for all of us. Hope it's not vaporware and that they just happened to put the miner in a Cooler Master mATX/ITX case

Well, it's been a while boys. Bitcoin near the previous ATH and all alts in the red. I like the action we're having right now, hope there won't be a huge dump again. The volume on USD has been absolutely insane today...

Like SFR said, profits overall for Altcoin mining have jumped off a cliff and most cards will make ROI around 10 months-1 year due to this. The A7s are pretty much as reliable and durable as it gets nowadays, but they're unfortunately OOS right now. I'd just wait for the next batch and see if you can get the miners you need. Your electrical cost is fine, I used to mine at $.065/kWh. Some people also bought Ebit miners and they reportedly run just fine but I don't have personal experience with them. They also have an all Chinese GUI (have they changed it?),which isn't a problem because I am Chinese, but it might be for some. Not like it's impossible to navigate without knowing Chinese.

3GB is enough for around 1-2 years, so I think you'll be alright with these cards. 6GB is best as the DAG probably won't catch up to there for a little while, and the specs on the 6GB cards are slightly better most of the time compared to the 3GB cards.

Your electrical price is way too high for mining to really be profitable at all. It's better to just invest in coins that you think will rise in price the most over a long period of time. The profits you'll be making will be tiny and ROI will be extremely long. In the US the average electrical cost is $0.11/kWh, yours is much higher than that.

Need this miner gone, no real use for it anymore even though there is profit left in it for me. Wife started to use the basement and my garage is full up so I cannot mine with it anymore (sadly).

Miner runs at 3THS because of a faulty blade. The blade has long been sold so I can't provide it to you. One connector is on the miner so you can easily pop on another board.

The miner also comes with a DPS800GBA PSU. It's rated for 1000W on 220/240V and 800 on 120V but only has four PCI plugs. The plugs got hot on the blade with only one plug on it. It probably won't melt or cause horrible problems, but it's just the Achilles heel of the setup. No use for the PSU ATM so it's pretty much free with the sale of the miner.

I only accept BTC payment so don't ask about PP or altcoins, no cash either. I'll only ship this to US locations, and you will pay for shipping. Escrow required.

Red Devils and Gold Sample cards are pretty damn reliable in my experience. Golden sample ones are top of the line binned chips and they usually do very well in most tasks. Gainward makes Golden Sample cards for Nvidia too, and those cards were very nice, but haven't heard from em in a while. They were clocked high out of the box and still had legroom for more OC, and had relatively low power draw.

Difficulty would simply drop on the main BTC chain and blocks would come at a regular rate of 1/10mins eventually with any sort of network disruption. With no userbase, and a price trend that will probably be downwards over an extended period of time, there is no reason for anyone to use S2X if the BCH situation is repeated. And for now, signalling is only intent. There is no guarantee that the signallers will switch to S2X.

I have:

R-BOX 32GH/S
Block Erupter
2Pacs and Compacs
Antminer U1
BFL Jally
Arctic USB Fan to cool your sticks silently

Just PM me your offer(s). Open to any offers atm  

Yes, you need a power supply for your miner. If you're feeling lazy Bitmain sells PSUs that work fine with their miners, you can also shave off a few bucks by buying server PDUs with breakout boards and attaching PCIE cables on yourself. Not that hard. Soldering is also an option if you want to skip the breakout board.

Bitmain has been okay with payment. They deliver but they are occasionally late and their approximation is semi-close. All batches state which month they will be shipped.

Ebit also sells their miners without power supplies, and again you need to supply your own. Same applies.

Ebit's trustworthy to my knowledge and they also deliver miners better than Bitmain's (but not in efficiency, Bitmain has terrible practices and sells used miners, bad customer service etc).


Also notice Ebit ships in October and Bitmain ships in November and only takes Shitcoin Cash. They used to take BTC but now they want to pump their useless coin.

S2X is held together by shoestrings and a little hope. With all the practices they're already doing to stay afloat (blending in with Core nodes because of the lack of S2X nodes) I really don't see much going for it. Miners can afford a loss to fake preference towards S2X for a little while, but the userbase just won't be there for it. It's a project that was doomed from the beginning. For most of us it'll be free shitcoin like BCH was.

Because it's just plain not profitable and 99% of the time except for projects that specifically state smartphones have an edge or something similar, desktop grade CPUs, GPUs and ASICs crush them. Besides that, your phone really isn't meant to run at 100% all the time. It's not exactly a little known fact phones have horrible heat dissipation. You're also competing with botnets with CPU power (Monero, for example).

This isn't the technical way to do so and I'm not sure if it's possible to disable it otherwise, but one guy that sold me a Compac (not a 2pac) put some dark nail polish on the LED and it barely shines through. No electrical issues on the stick with it on to my knowledge. Dark tape might work too.

Loving the visual guides! Gives an idea for all of us how proper sound insulation should be done and what precautions to take. Overall surprised how much quieter the Avalon 7s are compared to my S7s even without the wind tunnel, 58 decibels should be more than enough for home mining if you put the miners in a basement or garage.

In addition to all of this it looks like they just scraped the Zeusminer logo off of the Zeusminer that they took the photo with (lol, or Photoshop). These guys have been proven to be a scam a while ago. Bitmain, Ebit and Avalon are the biggest three miner companies that exist right now and that likely isn't changing.

It's not just that, but they mine for extended periods of time. It's known Canaan/Avalon test their miners and their own rigs on Kano and that is fine; their quality is good and the miners they sell aren't like some Antminers (and they don't mine for long periods of time with em ). Bitmain also has terribly slow support and many times they reject perfectly good claims.

I used to mine in South Carolina (Charleston), so I think I can speak a little about that. In hotter areas ventilation is especially important, it's good to install several fans in wherever you are keeping your miners and they'll run fine(large ones with high CFM are good for low noise, remember to have airflow in and out). Also remember to test for a little bit after you finish setting things up to make sure you truly have everything done right.

Lol, no? This is the Bitcoin forum and all discussion should ideally be about Bitcoin miners. Bitcoin miners are plug and play and usually reliable to the point that you don't have to do much maintenance, and it should be common sense to first at least plug your electrical cost and hashrate into a mining calculator to get a rough approximation of profit. As a general rule of thumb, greater than $0.1/KwH don't mine(Bitcoin), less than $0.1/KwH it's fine to mine.

It's a known fact Bitmain uses miners before shipping and to my knowledge they don't do anything about it even if you do happen to tell them about it. For Bitcoin, Ebit, Avalon and Bitfury miners if you can get your hands on them are better and probably not used. It's a shame that this, combined with expensive servicing if a miner breaks that makes Bitmain terrible to buy from. Not to mention it's them behind the recent and upcoming forks, which is more political.
