Topic: Antminer V9 4TH - page 8. (Read 19995 times)

I can run a 900W S7 with a single fan at 30% and it's a heck of a lot quieter than a stock S7.

Perhaps another (two) way(s) to look at this particular product... (at least this is how I am looking at it)...

I have been running some of Sidehack's 2Pac sticks on a small rig, and mining directly to a paper wallet that I'm stashing away for the BTC $500k days they say are coming. Or whatever. Rainy day wallet. The sticks have been religiously cranking away at 260-300 GH/s and its been an interesting learning curve and fun way to soak up some stuff. However, I wanted to do something a bit more effective towards my paper wallet mining, and had been considering a used Antminer S4 on eBay. At 2 TH (and 1300 watts) I've been debating the plusses and minuses of doing this. The units are cheap, and the "ROI" or profitability of the coins aren't as much a consideration for me as just slowly, quietly stacking some coin in the corner.

S4's have been averaging $275 - $350 on eBay. I'd have preferred an S7 for the additional hash rate and better power consumption, comparably. If the real investment in my paper mining is the power cost alone... so be it... but at $1,200 or so per S7 lately on eBay, it didn't make sense. That's more than I want to invest.

So these new V9 units are attractive to me for that reason alone. $345 and 4 TH okay... now we're talking. Better efficiency than S4, better hashing power than S4... sweet. Sign me up. So that's one way to see it.

But then... a good friend of mine told me what he's been doing with one of his S9 units. He bought extra S9 control boards on eBay and has been splitting an S9 into "three" functional units. You get the benefits of S9 power efficiency, and about 4.5 TH of hashing power per board. So he can split the hashing power across three different coins if he wants. In my case, I could break out a single board on an S9 unit to be the "paper wallet" board... and let the other two do what they've been doing.

Being scammed by a Chinese company doesn't give you the right of insulting all Chinese (and latinos while you're on it). My "high horse" is not that high.

So just for shits and grins, I clicked on the email I received from Bitmain to order 5 V9's.  The add to cart button works, but nothing appears in your cart.   Shitmain should put more thought into the operation of their website rather than re-branding S7's.

Cool. Ride your high horse next time you send $100,000 wire transfer to a Chinese company who suddenly changes the terms of your agreement as soon as payment is received and let me know how it plays out for you.

Well I sharpened up the pencil a bit and this is the results. Factoring last two years difficulty increase and how much they are asking/projecting clients get in return compared to network difficulty increase.

Thanks for your bigotry.

I agree. 100%. Here in America.

You are dealing with the Chinese now. Business customs and practices are so totally different that one can’t even begin to explain. You just have to work with them a few time and you’ll get it.

The label IS important. The label DOES make this a new item. This is how Chinese business works. If they are selling it and they are calling it new and they rebrand.  It’s new!

That’s why dealing with the Chinese and Latinos is a total PITA. They’re still developing.

Absolutely, their sales record has been excellent in a market with enormous demand for past few months.

However my point was that it is maybe not ideal to present a new product very similar to old one with such obvious image manipulation.

Step 1: remove sticker to expose s7 label
Step 2: list on eBay or amazon for $999
Step 3: profit

Their miners already sell pretty well and most people probably won't even notice the new label on the miner. I don't think they've had many issues with product marketing recently considering their S9s sold out in minutes just a few weeks back.

Haha, this is usually quite accurate statement! As pointed out above already, they did not really bother to ease the concerns with their product marketing. If they wanted to convince the customer base that this is a brand new product, they probably should have hired somebody with better Photoshop skills to do the sales images

Not stating anything about the product, but that looks just about as bad as it can.

https://en.wikipedia.org/wiki/Duck_test
If it looks like the S7, specs sound like the S7, and it performs like the S7, then it probably is a S7.

Maybe, but the part about being a new chip doesn't make sense to me. They do have the mask already for the old S7 chips I guess? They may have just ordered more and use a new name for them. Newly produced S7s does seem to make sense overall, but if that's the case they missed the wave badly.

It sells much better than if they would sold those as S7 miners like they are.

"OOOOHHH NEW MINERRSSS!!!"   vs.    "Oh that's just a old S7, booooooo."

The T9 used the SAME chip as the S9, just fewer of them running at a higher voltage for less efficiency.
These look likely to be a relabled S7 chip.

 It's on the US site (now) - but forget about it unless you have SUPER cheap electric, at my VERY LOW electric rate it barely nets $10/month (and I'm in the 3'd LOWEST rate area of the US).
 They SHOULD have introduced it a month or two ago, it would has sold like hotcakes then.
 My bloody A2 farm is MORE profitable per $ invested than this thing is.

 STILL the insistence on that BCH garbage for payment.

 

Considering that you may not have this hardware until sometime in march I have taken the yearly average of 10% network difficulty increase and applied it for when you are expected to start receiving the hardware.

Here is an estimate of the network difficulty as of March 2018.

Results for BTC/USD estimated trading price at $8500.00 USD
Estimated March 23 2018 Difficulty 3,811,165,475,251

I think most of you have forgotten that Bitmain sold tens of thousands of used AntMiner S7s when they upgraded to the S9 a couple years ago. They sold the used S7s with minimum order quantities of 500 and they specifically called them out as being used with no warranty. Considering they probably sold all of their used S7s AND these have a different chip in them, I suspect the V4 is probably a 28nm version of the T9 that was easy and fast to throw into production a couple months ago when Bitcoin/Bitcoin Cash were soaring. Think about it - getting in line for more products with TSMC probably takes 3-6 months of lead time. The faster/cheaper route when attempting to catch the wave would be to use a 28nm node that aren't competing with all of the 16nm stuff.

maybe they should just sell more antminers s7-ln, I miss mine. sold it too early
