what would shipping be to 49783? (northern mich)


I'll buy them both today if shipping is reasonable.

still available?
23  Bitcoin / Hardware / Re: [GUIDE] Undervolt antminer s1 [1.19W/GH at the wall] on: January 14, 2015, 03:54:36 AM





current info: running time - 15 minutes
GHS: 473.69
Watt: 469 at wall

when i start it up several of the blades produce a lot of errors, but it equals out over time...

i will post stats after 6 hours again

Why not do away with the fans, fun at full voltage, and just submerge the stack in mineral oil ?

I think the bitcoin price is only deflating to it's proper market price.  I'd say it'll drop to $25-50 and stabilize there.

and how much profit do you make now?

Also, I don't know if you're aware but there's a thing called a "bitcoin mining calculator".  What it is is essentially a calculator that calculates the potential earnings for bitcoin.  You can use it to see if something would be profitable to mine with.

Try playing around with it with a $0.00 electricity price and 0% pool fee.  If you can purchase equipment at $.20/GH then it's a solid investment

I don't mine.

You asked for an example of free power.  There it is. 
27  Economy / Service Discussion / Re: CEX.io Halts Cloud Mining Service Due to Low Bitcoin Price on: January 14, 2015, 01:51:13 AM
free power? can you please give an example of free power. do not tell me about solar power because it is not free.
you need an expensive investment for that and it's not working if you live in Sweden or even in Eastern Europe where 6 months is winter.

My rent is all inclusive.  I pay x amount per month regardless of the amount of power I use.


I have free power.  I've identified 4x 15 amp breakers that I don't use so theoretically I can run 6000 watts at my place with only the upfront cost of the equipment.

Approach bitcoin in any centralized way of doing business is very dangerous, soon many large firms will go broke and mining back to the hands of home miners. Home miners are not fiat profit oriented, while large organizations are not

what you said makes no sense.   professional miners have lower costs than home miners because they use scale and location to their advantage.  if the professionals get priced out because of the low btc price, there is no way that home miners can take up the slack as their costs are significantly higher, and it'd be very unprofitable.   home miners aren't a 'charity'.  they mine for the reward, not just to power the network.  if it was significantly unprofitable, home miners can't afford to do it.   (and if they want bitcoins, they would just BUY them, for less cost than mining them).



Lots of home miners have free power and are only running under 1TH as a hobby.  There'd still be plenty of power securing the network if the big farms shut down.  

Personally I'm hoping for a price of 1-150$.  This would see the farms disappear very fast
29  Bitcoin / Mining support / Re: any benefit to having each miner as its own worker? on: January 09, 2015, 09:18:44 PM
I was just asking because on BAN you can use port 3334 to lower your difficulty.  IDK what that means.
30  Bitcoin / Mining support / any benefit to having each miner as its own worker? on: January 08, 2015, 03:37:30 AM
I'm currently running 2 antminer S1s, each on their own  worker with BAN.  I plan on added 2 more S3s.  Right now I'm using the slower HR port.  Should I just have everything on 1 worker?  Is there a difference?

Like the title says.  I don't pay for hydro so I'm not worried about my consumption at all.  I want to mine out of my apartment so noise and hashrate are my only 2 concerns.  What would be the best I could buy that is quiet and under $1k

Buy antminer S5 and a quite fan. Replace the fan on antminer S5 and you have a quite high hash machine Smiley

S5 is  341$ for 1155 or 0.295$/GH

2x S3 is 200$ used oon ebay for 886 of 0.226 $/GH
32  Economy / Service Discussion / Re: Do i earn money from genesis mining? on: January 07, 2015, 04:02:41 AM
No, it is a scam, just like the rest of cloud mining. The only people who make money are the company. You will receive back far less than you pay them.
Cloud mining is actually a bet not a scam, take Hashnest (they're owned and ran by Bitmain) Currently .001278/gh and 57.41% of earning is fee. With .00001839 which gives you .0000104823 after fee's which means in 121 days you will roi (at current difficulty) The last two times difficulty has been decreased but we will probably see an increase soon. So if you buy into cloud mining you are betting that you will make more than current price over time, also the fee's go down when the price is up since electric is in fiat.

Not a scam but a bet.

a sucker's bet marketed as a breakthrough is the same as a scam

Hello, I have the Rockminer New R-Box running with 110Gh/s and have realy an result of very view outcome, I use the Cgminer at eclipse, wanted to ask that if with my Conditions are 0.002 any Round of BTC normal?

how long between rounds?
34  Bitcoin / Mining speculation / Re: The difficulty HAS BEEN REDUCED!!!! on: January 06, 2015, 02:14:20 AM
What kind of idiot considers higher difficulty to be good?

The price is steadily dropping also, is that good?



price dropping is good for the home miner.  Lots of operations are operating on razor thin margins.  When price drops, unprofitable machines get turned off and difficulty drops with it.
35  Bitcoin / Mining speculation / Re: The difficulty HAS BEEN REDUCED!!!! on: January 05, 2015, 10:12:36 PM
I am Glad to see a reduction in bitcoin difficulty, I was getting ready to pull the plug altogether Smiley

sorry to break it to you but it's going up 15% on this next jump.
36  Bitcoin / Hardware / Re: What's the quietest, most power miner if you don't care about power efficiency on: January 05, 2015, 10:02:53 PM
Antminer C1.

I really hope Bitmain design a new C2 with the S5 chip.

4x S5 chip would be quite nice
37  Economy / Computer hardware / Re: [WTS] 4x Antminer S3+ B11 on: January 05, 2015, 01:13:49 AM
Do they come with a PSU or are you just selling the miner?
38  Bitcoin / Hardware / Re: What's the quietest, most power miner if you don't care about power efficiency on: January 04, 2015, 09:17:19 PM
I think your most powerful miner will be the most efficient ones as well, Moore's Law and all that.

Well maybe not necessarily the most powerful.  Best bang for buck so to speak while trying to make sure I don't fall off the end of the curve in 3 months.  

I bought 2 ant S1 with a corsair rm850 to get started.  I hope/plan to ROI on the S1s (not power supply) after 60-90 days (assuming 15% average diff increase) and now that I've got my feet wet and have learnt so much I'm trying to line up what my next move would be.

Please don't say, " just buy coins. Don't mine."  I'm doing this for fun and only hope to have a hobby that is break-even.

At this Diff on my current pool I'm averaging .004 BTC/day, so 0.0000111/GH.  My thoughts are that 1) I can stay a few generations behind and as long as I'm purchasing at $0.25/GH (or 0.000877 BTC/GH) My ROI would be not too far out each time I upgrade I keep a low risk.

Example

buy Ant S3 on ebay for $110 USD and just swap out one of my S1s, then do that again a month or so later.  The thing I hear about the S3 is that it's loud.

Or 2) Get a Spondoolie SP20 for $425 (again $0.25/GH) and invest in a second rm 850 to power it up.  Again I hear it's loud but now I'll have some hashing power behind me and I won't be too worried about falling off the end of the curve for at least a little bit.

or 3) Ant C1


Is 1 Sp20 louder than 2 S1/S3s?

1. S3 are not loud in comparison with S5 and Sp20. S5 is the loudest, followed by SP20.
2. One SP20 is louder than three S3, but less loud than S5 (at least when Sp20 is down-clocked to 1.35 TH)
3. where are you getting the prices that you quote, especially for SP20? The price is $498 per each SP20 if you order 3.


I'm looking at buying used.  Ebay has some good deals from people rushing to upgrade to the new units with the best hash/watt ratio.  I'm not worried about power consumption so I'm planning on taking advantage of that.

Before the S5s were announces S3s were solid at $200 but in as little as a couple weeks they're already plentiful at $155 http://www.ebay.com/itm/201256643156?_trksid=p2060778.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT I bet he'd at least consider $200 for 2 units or

I'd bet that this trend is only going to continue.

antminer s-3 with this fan

http://www.amazon.com/gp/product/B00A460TK6/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1


will result in near silence .  One fan needs a slight mod to the edge of it. 

I have two from my s-5 sitting in a box.

 they work okay on the s-5 due to the open  case design ,but  they work great on the s-3.

Do you happen to know the CFM on the fans?

Would they work with the S1?  The S1s I bought don't have stock fans with PWM they are hard wired in and always run at full clip.  I wanted to change the fans out but no point in investing $ on an S1.  I can put them in my room with an open window (good old Canadian winters) and keep the internal temp at 25C but can't sleep with the fan running 100%.   It wouldn't be a bad investment if I'm going to use them on something else later

I'd be willing to buy them off you if they have PWM.

  shipping them to canada is costly I am in the states. 

Sorry, forgot to mention.  I live in a border town so I can pick them up in the US and bring them across myself.  There's a shipping warehouse that we get stuff sent to.

How much would fair price plus shipping to 605 Ridge Street, Sault Ste. Marie, MI 49783, United States be?
