Topic: ANTMINER S4 2TH/s, Batch 1 on Sale this week, shipping before Sept. Ends - page 6. (Read 33477 times)

On a related note, BTCInvest needs to add a Mine + Hold (less power) to their tallies, where you cash out enough BTC at the current exchange rate to pay your power cost, and hold the rest.

It's not wishful thinking, unless your power company charges you a constant rate in BTC for a kWh regardless of the exchange rate. At $400/BTC, once the difficulty updates in a few hours someone running an S1 at the default 2J/GH with 13c/kWh power will pull in ~$1.24 a day in BTC, and pay ~$1.25 in power costs.* At $800/BTC, you'd still be making $0.62 a day.

Mining calculations are much more complex now than they used to be when you could effectively ignore the cost of power, especially when you're BTC rich/fiat poor and considering buying hardware with Bitcoin. In that case, you're converting real Bitcoins into hardware in the hope you will produce more Bitcoin, with a very large variable operating cost that depends directly on the price on BTC. If I convert 14.9BTC into 14TH/s with the Prismas and the price stays at 400 , at 10% increase per jump decreasing by 5% per jump, I would only make back about 8.5BTC before I would shut it off. Less BTC than I started with, so bad deal obviously.

If the price immediately jumped to $800 though and stayed there, with the same network conditions I would pay off my 14.9BTC after 28 weeks, even with paying power costs weekly. The massive caveat here is that the network difficulty will behave much differently at $800 than at $400.



*That stat in itself pretty amazing. Without the price going up, there is a lot of relatively recent mining hardware that is going to be shutting off or sold for pennies on the dollar to someone with cheap power. It's only going to take another doubling before people paying 6c/kWh are shutting off S1's, and everyone over 10c/kWh will be effectively mining for nothing with every KnC Jupiter, Cointerra, A1, S2, or HF board made.

when the buying STOPS, so does the KILLING !
BM please revise or else there ain't gonna be no sales at all.
I put my word in here, if the revised price is feasible, I am ordering a minimum of 30 x S4's

If this was just a test on how the community would react, it was a very bad joke not in favor of Bitmaintech.

Price is back to 0 USD (0 Btc) . i think a fair price would be around 2 BTC and they should price their product in BTC only.

@BITMAIN, I'd like to say that this is VERY disappointing, I really had high hopes for the S4. A very bad move in such unfortunate times, it's clearly driving people away to SP and AM, which I am considering myself right now.

S3 are NOT currently on sale for 0.58 BTC, and if you want to buy on ebay, it cost ~$330=0.79BTC, so four would cost you 3.16BTC.
BTW 4X330=$1320 and IF you add PSU, it will get close to $1450 and maybe even a few $$ more.
So, where are savings-please don't tell me about coupons because I got none.

I asked was told in a email discounted went to by one with  bitcoins today some one told me a how to buy one i was to late .


they cleaned the site up some and dropped the S4 price so well see .


 its a good  thing when every one stands up it does work they could have last a lot on this one and may still once we see what it does and how much.   that's the  really big question  how much.

If anything there prices  should be lower if they follow there own policy.

ZiG

EDIT...: $1450... I am NOT buying this S4..."no way, Jose"...

I will go with SP-Tech SP20 for $1190 ...1.8TH...Later...

+1

Personal attacks aside, this is the truth:

If the hardware costs more in BTC than you can mine in a reasonable time, don't buy it.

If you think the BTC is going to go up, then buy BTC.

Mixing currency speculation into your ROI calculations is just wishful thinking...

Dumbass if you want to speculate on BTC price, do it right and BUY BTC.

The point here is that you WONT mine back BTCs that you spent on the S4

Buying ANY mining gear right now (all the current offers) is giving btc away. Not just S4

If I listen to you .  My move is go to coin base buy 4 btc for about 1700. 

The use  2.32 btc  to buy a four  s-3s' and hold the rest as coin.

BTW anyone that buys an s-4 and does not do this instead  really is self destructive. 

Most of you have a mistake in your equations. They are based on wrong precondition - you somewhy think that BTC's exchange ratio will be the same as now. Try to imagine it will be 600$ in one month, when the miner will pay for itself in this case?

Trust in BTC, otherwise everithing doesn't make sense...

May be it's better to wait for an upgrade kit for S2?..

SP20 is specifically designed for home use. That why it is not rack-mountable, does not come with a power supply, and has the slogan "home mining is back" on the product web page.

My take on the Bitmain product line:
S1, S3 - designed for home use (no power supply)
S2, S4 - designed for "datacentre" use (rack-mountable, integrated power supply)

Not as I said won't be buying a S4 at this price.

Guess I won't be getting any S4s. Whole lotta nope.

whats your reason to give btc away?

I am running 4 - S2's, 6 - S3's , and 3 Tubes and I had planned to sell the S2's on eBay and replace with S4's but screw that.

Canary is putting a GB for the new Prisma tube 1.4 th and I have been very pleased with my current tubes so that is what I going with. Bitmain not that you give a flying F but at this price you lost my business.
