Then i bought S5 miners > no profit (clearly bitmain overpriced them)
Depends on WHEN you bought them - if you bought them early in 2015, you should have RoIed them fairly easily unless you're paying more than 10c/KWH. If you waited for June/July timeframe, you would have needed VERY VERY cheap electric to have a good chance at RoI with them (unless you did like I'm doing and sold them for enough to achieve RoI). There isn't a lot of labor cost to running a large farm - MegaBigPower has mentioned having a staff of 12 (IIRC) for their BIG Washington farm. That's not much staff needed for one of the bigger farms in the world. S5 willl not be profitable in the next quarter even if you have very very cheap electricity. The difficulty will at least double when the 16nm comes out.

S5 is bloody near not profitable NOW unless you have VERY cheap electric. That's WHY I've sold most of mine off (and am trying to sell the last one and my SP20).
It will take time for the difficulty to double again due to the 14/16NM generation, especially given the reported yield rates from folks like TSMC on that node right now. On the other hand, diff has been rising quite fast since shortly after introduction of the S7 just from the "last gasp" of 28nm tech.....

Even if you get a very good price on the elecricity. There is no way you will make ROI. Remember you have to buy a PSU too. Which makes it unlikely to see any ROI.

I pay 18 cents. It's less then you OP but it is not giving me any profit. I feel bad i started mining al together. It cost a lot of time and no you won't get you money back.

I suggest selling gear or finding a hosting center. 18 cent's is to much to pay on electricity for mining. And add cooling on top of that, you are going to lose quite a bit over time mining. But with high difficulty changes I think sooner you get out of 18 cent electricity the better. Hosting you can easily get 10 cent's or less, so even if you send it somewhere for hosting you are far better of.

The power supply you can resuse for other things later though - next generation miner, next computer build, etc. - so if you don't fully RoI the PS it's not a big deal.

Why do people want to mine? Is it because they want to "contribute" to bitcoin network? Is it because they want to "print money"? OP is in the latter camp, based on the question "21 cents per kw, any way to mine?" He/she is keenly aware of her electricity cost and cost is top of her concern, in other words, she's highly concerned with $$$. I'm not judging her, I am also highly concerned when it comes to my money. However, I've been here long enough to KNOW it's too late to mine if you're a regular home miner with limited resources. This forum is littered with noobs asking if they can mine with x.xx cents per kw, as if that's the most important question. It's one of a series of questions you should ask or research for yourself. There are important factors you should consider, one being electricity cost, another being the diff factor, among other things. They have no idea how much diff is rising currently. If they jump in, because of $$$ signs dancing in front of their greedy eyes, they're going to be in a world of hurt later.

Why a particular person wants to mine VARIES WIDELY.
Many or perhaps even most want to make some extra money, but some are more about "want to support (whatever)coin" and such.
Realistically, the cost of your electric *IS* the single biggest factor in mining profitability. Yes, there are quite a few others, but if your electric is too expensive none of the other factors MATTER.

Right now i would not by any miner. Just wait for the next generation of miners. The current batch is way overpriced and you will make a big loss on it.

It all depends on electricity price I would say. Electricity price can make or break you. I'm doing some moving around with miners doe to this. But this 21 cent thread ... 21 cent day's are gone with current products. So there are still people out there that are able to mine, just takes lower cotst. And hopefully a little more value on btc would be nice for miners.

Not true PSU's are actually pretty good assuming you don't buy crap. I have multiple PSU's that I have used multiple generations of miners. When I sell miners I keep the PSU's so I have mine paid off for most part, I will buy one if needed. But PSU's you could even sell after to. It will not be the difference between ROI and not ROI I don't think on most miners.

The only profitable coin to mine at present is the Ethereum. But it is with GPU not any ASIC. If the price drops, it will not be profitable.

Yes. It is still possible to mine Ethereum even with $0.21/kWh power price. But it might not be in the future as the difficulty is rising fast.

it dropped already i assume it's not proftibale anymore, since even without the drop the diff started to increase fast now with the drop it's done

Will you ROI on your GPU's? Unless there is a chance of ROI I don't consider it profitable mining. Just mining more then electricity.... is not enough for me.
