What miner do you have now and how much you mine? How much is electricity kwt hour in your country?

Still got the same S3s I purchased last year from the early batches (1,2 and 3).  They're turning 1 soon, and I'm sure I'll have a nice party for them.

Of my original 9, 8 are still functioning within acceptable parameters.  The poor one that is no longer with us failed on me at the beginning of the year.  I get about 3.6TH/s from them.  Cost of electricity is around $0.10 per kWh.  They are still squeaking out a profit...

Thank you so much for sharing! !!!

i'm  buy antminer s5
i don't know still profitable or not mining bitcoin right now. if profitable i want ordered again one or 2 again maybe 3

no miners, but if the new generation is promising, and arrive before chinese start investing in it too(i doubt, but still one can hope) i may consider purchasing one of those miner that work at 16nm

before that i want to see his spec, consumption and hashrate ratio, because my electricity is too high here

I have few usb miners but i am thinking to get rid of them.
When i bought it was interesting for me, but now half of them work and half not.

Oh!  I forgot about my USB miners :).  I've got 5 Antminer U2 that give me about 9GH/s.  I have them pointed to -ck's solo pool... because you never know.  They cost virtually nothing to run (they're plugged into an rPi).

I'm about to buy 2 U2's to start experimenting with mining... No chance of getting ROI, but that's not my main motivation  8)

Unless you've got virtually free power, or you get your mining hardware for virtually no cost, you've got almost no shot at ROI with any gear.  For example, let's take a look at the S5.  Right now, new from Bitmain it's $360 (1.434BTC at their current conversion rate).  Let's just pretend there are no other costs at all (you already have a PSU and no shipping costs).  At the current $250 per BTC, even with only a 2% overall increase in the network hash rate per adjustment you will not ever make ROI with $0.10 per kWh power.  Make that adjustment 1% and you'll start to see a profit in about 300 days.

So, I'm glad your primary motivation isn't ROI :).  Also, I just wanted to point out something that may be obvious, and forgive me if you're already aware.  The U2 is a SHA256 *only* device.  I mention this because of your forum name.  If you plan to point those U2s to some alt-coin, ensure it's SHA256 or the miners won't work at all.

Thanks for the tip... I actually didn't even thing about the fact if it was sha256 or scrypt, i just wanted them to experiment with mining...

Indeed, my nick is altcoinhosting, but that's actually because i regged a domain altcoinhosting.com, offering users the possibility to pay with altcoins for their hosting. I'm planning to exchange those altcoins to BTC anyway  ;D

I have

Bitmain S3
Bitmain S2
Bitmain S1
Bitmain C1
BTCGarden V2
Bitmine Desk V2
Gridseed G-Black
MAT 256Mh

5 S5
1 S3

that i use


four worthless Script miners i use from time to time for fun.

 one of my scripts is a G-blade black the rest are Zeus Miners.

but i all most always have a total of 6 miners running til i can afford more S5 or find deals on used ones like i did the other day. and may be buy  a titan and A1 or A2 script miner.


O yea forgot a  


S1 that sets most of the time i want to upgrade not to a S3,I'm hoping one or two things going on the forums lets me upgrade it to a more useful thing.

 have been thinking of buying one of these BTCGarden V2.


0.0855 per KWh without taxes and fees added. I avg  around 350 $ total power bill  a month for the house if I run them 24/7 if I don't a little lower.


and my S5 have paid for them self i can't complain by that i mean i reinvest what they make to make more :)..!!!!

All S3s now.

Two S3's
1 "new Rbox"
1 S1.


I mine 24/7, it's freaking complicated and retarded.. like 12 cents then they start charging more if you use more.. so you get charged 12 cents if you use like 1/10th of a KW/H or like 25 cents if you use 10 KWH...

USB Miners arent expensive, it's a good way to start mining and understanding the concept.

You are completely right, there is no ROI, but it's a good chance to understand how it works the mining, and motivate you to upgrade to the next level :)
Good luck altcoinhosting

Thanks  ;D Altough i'm not completely sure my wife will like it if i take mining to the next level (our Kwh rate is €0.27  :-\ )...

Unless you electricity is free, there is no profit :P - my opinion.
But for experimenting is brilliant.

No, she'd probably be pretty upset.

€0.27 per kWh means an S3 will cost you roughly €2.20 per day to run.  Currently, that S3 expects to make €0.97 a day.
For an S5 you'll do a little better, but still not going to make anything... €3.82 to run a day, expects to make €2.91 a day.

Might want to hold off on taking it to the next level :P

Not only would she be upset, for once she would have a good reason to be upset  ;D

I actually wasn't planning on taking it to the next level anyway, i was aware of the fact that the more hashing power i burn in my home, the more money it'll cost me. Energy prices in my country are insane...

I'm just going to use my (future) U2's to mine some BTC and to experiment. I'm aware of the fact that running a server (i've got an old HP Proliant gathering dust) with those 2 usbsticks will consume a lot more power that can ever be made with the BTC it'll mine... But i don't really care  8)

From this great calculation there is no profit.

Got 4- S5 1- Avalon 4.1 and 3- S3.

Still make profit!  ;D

Wondering if we would be able to get one of those 16nm miner.

I laughed pretty hard on that one ;D

Rather than fire up an old HP server, you can easily plug those sticks into an rPi, or even whatever laptop you're currently using.  I've got 5 of them in a powered USB hub, and that hub is plugged into my rPi.  The rPi has cgminer 4.9.1 compiled from source running.  I point them to -ck's solo pool because you never know :).
https://i.imgur.com/v4QRxPJ.png
The cost to run it is virtually negligible... the U2s draw about 12.5W total and the rPi about 2.5W.  15W total consumption costs me about $0.04 a day.  With your insanely high electricity costs, that same setup would cost you about €0.10 a day.  Since you're only talking about 2 U2s, that would be a total power draw of 7.5W and about €0.05 a day.  Pretty sure you could slip that one by the wife without notice :P.

Of course, solo mining with only 2 U2s, you've got about a 1 in 617589 chance a day of finding a block at current difficulty levels... but at the cost of playing, it's worth it.

no miners anymore (I had FPGA Acarus, Avalons and few KNC Jupiters back in good old times), reg. electricity ~0.2$/kW, so even new generation will not work for me:(

I think one thing worth mentioning here is that all of the numbers provided thus far are based upon current conditions: the current difficulty, the current exchange value of BTC, etc.  As things stand now, with BTC valued about $250, you've got to have extremely cheap power costs to break even, much less make a profit from mining.  The hardware you're using obviously has an impact as well.  Using a GPU to mine BTC is absurd because of the high power to hash ratio.  Even the currently available, most efficient ASIC gear is still between 0.4 and 0.5W per GH/s.

Things change quite a bit if the exchange rate of BTC goes to $1000 a coin, or some new hardware comes out at 0.1W per GH/s, or the difficulty drops dramatically.

It's actually a very good idear... I am, however, one of the few reasonably tech savvy guys on the planet that doesn't own a raspberry... I do have an old neoware CA22 laying around. I might try to install a linux distro on it, and run it as a server. It also has 2 usb-ports, so i might just plug the U2's dirctly into the thin client (don't know if this would be possible, with the heat and the fact they do draw a couple of Watts).

They're well worth the minimal investment.  The new ones will run some version of Windows 10 (if you're into that sort of thing).  At $35 (not sure what they're priced like in your area) they're a steal.  Of course, getting that old neoware up and running might be a fun project, too.  Not too much power draw, and those USB 2.0 ports should be able to provide enough juice to drive the U2.

Have 2 BFL Jalapeno's (16gh total), 2 S3+'s (averaging a bit above 1th) that I still run. Could run my S2 but its too hot for me to do so until winter comes around again. I probably should get rid of my S2 and my SP10 (or the bad ebay buy). May get some U2's just for fun as well.

i have a shitty little scrypt miner that wont ROI unless we have another alt bubble

I had 3 S3's that I sold and bought an S5 with. I'm looking at getting another S5 and then probably an S4+ two would be amazing :P .


Check out my thread for ROI here guys if you ever question what S5's will do in your area.

I have 10 Antminer S1 and some Metabank Bitfury miners.
All of them is downvolted, so it uses about 1W per 1 GH/s.
Electricity cost is $0.05 per kWh.

Only kept 1 Gridseed 5 chip I bought locally in my early script mining days, just for the lulz ;D Mining at 0,22 $/kW/h, obviously not profitable, but I like the little thing :) It's a bit like a token, a reminder, it was the first one I had.

5x 700Gh monarchs
20x 16chip bitfury boards (undervolted) and 30 spares
4x Avalon3 blades (undervolted) and 2 spares
2x Antminer S1 (undervolted) and 10 spares
2x Technobit hex4m minion boards
1x Habanaro
3x Asicminer BE200 tubes (undervolted)

Tons of BFL 65nm stuff collecting dust.
Tons of first gen Asicminer stuff collecting dust.
Some Rockminers 32Gh and 100Gh gathering dust as well.

Power is pretty cheap here and have a solar kit on the way.  As long as I keep it around 1w/gh or lower I am good. ;D

Remember when my two HD5830's+Geforce 260 made more BTC than all of this combined. :D

I am using Radeon sapphire HD7950 and is giving me 300kh/s on scrypt coins, I am using free electricity.

I have a few antminer S1's but I currently do not have them on because of the summer heat. However, I may consider turning them on within the next week or two.

If anyone needs hosting (I see some heat complaints) we're the lowest cost option. $63/kW, located in northern Canada.

Antminers: 1x S3, 1x S5.
I plan to acquire three more S5's over the next three months. Working on a discounted power option to keep things profitable.

Correct me if I'm wrong but if 5 usb miners find a block on CKpool don't you have to mine the block first. Wouldn't that take another longtime do solve it.

you have not actually found a block on the pool, everyone else have contributed to find it, it's basically usless to find a block in the pool and not only that, but finding a block when you mine in a pool is not the same in finding it in solo

5 of most usb miners will not get you anywhere very quick.  A lot of pools have minimum payout so look at that if you are truly mining with 5 usb miners.

And chances of solo is very very bad.  It could happen but just such a slim chance.

I m new here...antminer s5 is profitable?

2 gridseeds gathering dust
1 antminer s5's (was going to buy another but the price jumped up)
2 antminer s3's (i want a few more, pm me if you have some cheap)
3 Zeusminer Thunder x3 (these drink power like crazy)
2 Zeusminer Blizzards (these are what got me interested in mining)
5 loose hashingboards+ heat-sinks and fans ziptied over them from a damaged GAW war machine i think

i pay around 0.04 cents kwh on average for commercial power on off peak hours
I turn everything off during peak hours except today with my scrypt miners because whoa! :o

If you've found the block, you've already mined the correct hash to add it to the blockchain.  There is no more mining that needs to take place on that block.  Of course, finding a solo block with 10GH/s... well, at the current difficulty, you would expect it to take nearly 673 years.  That hasn't stopped me from pointing my 5 U2s at ck.'s pool, though.  I've got a 1 in 245579 chance of finding a block today :).
