People never learn, the last company that tried to do the home miners thing with the sp20
Sold out to corporate greed as well.

That was the writing on the wall for me, I mean you know,that bitmain mines with the hardware they are selling you at the same time hows that a consumer driven philosophy? Its like the mining company selling shovel's and pickaxes while they mine the VERY same vein with jackhammers and drills what did you think was going to happen.

You guys keep buying thier ill made Chinese hardware flooding with pockets with fiat and BTC while they constantly lower thier prices to eliminate competition but that's not what realm happens....

The companies they drive out of the consumer market have invested too much to just leave, so they form thier own mining datorhalls and conglomerates which of course will destroy the diff.

I'm surprised you guys are surprised.

I said from the moment these units started selling its a better bet to buy BTC and let the big dogs destroy the diff and themselves especially when halving hits them.

Buy maybe 1 or two units from different vendors to help with heating lol that's all I would ever buy

i think it might work with all the batches! IF the speed of the slowest batch is applied!

This idea has been bugging me for the pass week  , I think someone has already asked this but is it possible to run the batch 9 hash board on a batch 7 miner running the batch 9 boards at ferq 625 same as the batch 7?

Next difficulty is going to be too painful!

i have to agree.. instead of selling out to corporate mining companies and make huge large scale miners that take 2000 amps to run and completely crash the bitcoin network, they should have done the smart thing and made small efficient home miners that are sub 300 watts with fewer chips and less speed at a decent price... that way if the large scale mining companies want to buy more to get more they can but it would not be as profitable.


in the end bitmain would have made more money because those that cant or wont buy a 1000$ 2000 watt miner that needs special 220 power installed in your home would have made up the difference.

this would have most likely resulted in less difficulty jumps..

yeah this is pretty good assessment . so if you want to  do somthing you can do what I did sold ½ my coins put them aside and if coins crash I will buy back in.

Cheaper miners are good. Cheaper anything is good.

In my opinion, I think it's safe to finally say that the industry is killing itself. Since Bitmain is the undisputed champ in the manufacture of the mining wars, they have serious weight and influence over the difficulty and hashing contribution to the network. Before this recent s7 mayhem, you'd be able to ROI and maintain some reasonable level of difficulty so you can rely on a certain level of revenue over time. But now, it's impossible to calculate and scale effectively.

For example, I ordered my s7's in the middle of November. On November 11th, the difficulty was 65million. Less than 3 months later, the next estimated difficulty hitting in 3.2 days, is 144 million (more than double). But the price of bitcoin hasn't doubled during that same time frame either.

Furthermore, each new batch of miners is significantly cheaper than the last. The batch 7 miners I bought cost me roughly $1450 each. 3 batches (and 4 months later), the price is half that.

So how can a bitcoin miner be able to predict an ROI anymore? It's impossible.

I see the antminer s7 price drops as a sign that bitmain doesn't care about bitcoin, or the miners anymore. They care about making money and adding as much hashing power as possible. Because lowering your s7 price by 50% within 3 months when you know the miner who bought 3 months ago didn't make $750 in bitcoin during that same duration of time, is just plain wrong.

This is the sad state of affairs for miners now. You used to be competitive for 6-12 months with equipment. Now, you're not even competitive a month later. And with resale values kept low in the interim, since bitmain is still selling versions for 50% less than what you paid, we're stuck between a rock and a hard place.

Difficulty is going crazy I wonder if they are full focus on making gear to have racks full during Chinese holiday's.   Also someday they will need a new chip.... I wonder where their dev is at.  They could have one ready to go or still need dev, no one knows.

All I know for sure is price of is going down a good amount with batch 10.  And I wonder with difficulty change what next one will be.  We live in interesting times.

Bitmain probably is too busy counting all their money then worry about our concerns.

I have purchased more then 30k from s-7.

They have lost interest in me so I can't chase them anymore.

Anyone want 9 .05 btc coupons ?

Are people still buying these?? In 2-3 more 20% diff jumps these will be nearly break even for $.1+/kwh areas of the world. Forget it when the bit fury stuff comes online...

Yeah I really wish the Avalon was priced more like the S7, would buy one also, even at the slower speed and worse efficiency.

If Avalon dropped the price to 600-700 I would buy some. But honestly the S7 is dirt cheap now. I'm done with Bitmain though after my Batch 9 failure rate and their "vacations". Had to buy 2 more to fulfill some orders, but I have none left now and won't be getting more. Honestly I'm feeling what philip is, don't really know what my next step is for miners.

yeah we got out about 35 units at 1100   but the s-7 at 925 or so is tough.

I no longer will buy from bitmaintech since they never gave me anything for my low hash s-7 from batch 1. 

 I sold the unit with a 150 usd discount because ti won't hash above 4500.  They gave under hashers about 67 or 70 usd for the batch 1.  I made 7 more purchases asking for a coupon to make up for the low hasher they never answered me or gave me anything.

So on Jan 31 they shoot me 9 coupons for .05   Which is okay but never addressed my underhashing gear.

While they used to be good to me a year or so ago..


 Right now they just ignore me .

I am in a funny spot as I won't buy from bitmaintech anymore and the Avalon6's are a bit too high in price.

Even if I got a really solid coupon from bitmaintech they no longer deserve my respect.  Sad but true.

Oh well.

Love the Avalon, really hope they can stay competitive with pricing.  Seems like all resellers are still selling them at ridiculously dated prices of $1300-1400.  Only our forum members like Philip / Kilo17 are doing members a favor in helping us get lower prices.  Even then, the batch 10 S7 at $780 is the final nail in the coffin for Avalon, unless they can come out with a more efficient / powerful box or drop price to the 600-700 to stay competitive.

That certainly does seem to be the case. Nobody else bothers to release new hardware besides Bitmain and Avalon.

Very good news, numbers are pretty good as well.

Antminers will take-over mining business it seems

It's 12CM as it's designed to fit the S7 120MM fan or any other Miners that uses the same size fan (ie S3, S5, Avalon 6, etc).   Works very well.  Here's a picture of it on my unit.  Noticed I used double tape temporarily until my longer screw arrives.

Very nice!!!!!!
Are those for 12 or 14cm?
