ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH

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.

Cheaper miners are good. Cheaper anything is good.

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.

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..

[nhando]

Next difficulty is going to be too painful!

[Seba13xp]

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?

[mavericklm]

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

[Marvell1]

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

[marvykkio]

soon end users like us, with little power will be left out, because it is diff is growing too will grow more and more, now with 20 th / s not going anywhere (I have 4 x s7), and in a few months, no They need any more, for heating only
I must only recover my roi 6000 Euros, then I sell everything and leave the world of btc final

Just like me, going to get my ROI asap and then leave all this to the big sharks. Home mining its dead.

Sounds like DOOM AND GLOOM.  I now have paid off my batch 1s and batch 3s and working on paying off my Batch 5s, Batch 7s, and Batch 8s. 

I am making a profit and doing it very nicely!  Where else can you buy a business with a ROI under a year, let alone you don't have to do anything buy update your firmware and make comments on the forum.  haha  Don't complain about the FatCat, outdo the FatCat.  Do the math, you can still make a profit.

[NotFuzzyWarm]

Ditto. My Ant farm has been self-sustaining and expanding for just under 2 years now. Yes profits are dropping but so far I have been doing very well. Even bought probably my last 2x s7's last night. For now from here I'll just wait to see what this years miners look like.

Well I think they're trying to move as much stock as possible before the BitFury chip comes on line. True- Bitfury rigs will go in their own Data centre. However, they are also selling chips soon. I saw one of their ads pop up on one of the sites i visit. So you might expect to see BitFury's own Data centre take a fair leap in hashing power and around June or July someone will be selling rigs built with the BitFury chip. It may be too late to buy one of those ?. However, I think Bitmain is wanting to get as much as possible out of the S7 before then. Also, i would think Bitmain is prepping to bring a new chip of their own to market by this summer to compete with the BitFury chip. Guess we will see.

True- but maybe keep one rig to play with.

[bitcoinboy12]

At the current price, newcomers will have faster ROI despite the higher difficulty but the problem is Bitmain itself doesn't care about their customers who bought right away when they launched S7. Things are a lot better pre-S7 days when you can ROI in 8 months or so with S5s.

you should not blame Bitmain for your decision to buy overpriced miners and not being able to predict reaslistic ROI times

cant agree enough. the advent of <0.3w/gh combined with bitcoin price going from 250->$450 was obvious kindling for a massive difficulty spike.

if anything, its best to buy miners just slightly after the peak of a price bubble whent he exponential difficulty growth begins to slow down once more (ie: around now, perhaps holding out for $400/BTC first)

[VirosaGITS]

I received my B9, it was packaged exactly the same as the B8, it appear unused or at least clean, smelling fresh of the factory with no visible use or damage.

Performance wise, as expected, but much better efficiency, i don't know what to say about this;

No but really, Bitmain did a pretty good "fleecing" on this one!

Bitmain used to sell their miners with a 3-4month payback window (estimated).  With the S7 all of a sudden it was 6+months?  But we still bought em! 

Then of course instead of the 5-6% growth rate required to actually ROI all that goes out the window with a little BTC/$ spike and Bitmain dropping the price to 50% so they can just keep selling!  Then doulbe digit increases again.  Brilliant!

At this point when I bought the S7 I did it mostly to lower my power costs over the SP20/S5, but I knew it probably would never ROI.  Mining has pretty much been for "suckers" past the GPU days.

yep

Bitmain dropping the price to 50% so they can just keep selling!  Then doulbe digit increases again.  Brilliant!

don't forget that at the same time they reduced number of chips thus making miners less efficient yet no one seems to care and still buys them a ton
