Have access to 800 amps

[aDude]

So I found out a friend of mine owns a building that has 800 Amps of 110/208 power to it. Its a warehouse that is currently empty and has security fencing around its perimeter.

The building is located in central Washington near ASICSPACE, Toom.im and the other large mines, so it would only cost $0.023 per KWh to run miners there (plus rent, ISP, etc.). This building has industrial air movement equipment in place and is upgradeable to 3400 Amps if needed.

Any ideas on how to make the best use of this space? Would renting out space at something like $75/KWh make sense to anyone? Or co-mine with someone that already has a decent amount of hardware?

or make yourselfs a hosting company

you can run about 150TH at 1w/gh with that feed.
if you're smart, you buy used miners at no more than $100-150 per TH
then spend about $30k on miners

boom, $6-10k a month after electricity - rent (hopefully less than 2k)

you MIGHT ROI in 3-5 months, then it's profit.

you can host, but that market is becoming saturated. So you can do a mix of hosting and mining.

You could probably do even better energy efficiency with some s3's, Bitmain might have something left, or look around bitcointalk forum.

I would go with the the most efficient miners, rather than saving a few bucks on older technology.   This will keep you in the game longer when difficulty increases.

You'll have to underclock sp20s or wait till chinese new year is over to buy s5's from bitmain. Or just completely wait for some s6's

I totally disagree with that.  If you are running a business, depreciation of capital assets accelerates as obsolescence increases. 
There is no comparison of $120 for 1th at 1w/gh vs $380-400 for an s5.  X150, This is not a few bucks.

you can buy the old hardware, hammer it out for a few months, then depreciate it on your taxes and move on to less older hardware.

in this year there are a few things to consider though.
best mining times where between 10/2014-now.  Meaning one should have started early october 2014.  during that time, the difficulty did not skyrocket.   used cheap equipment would have paid for themselves months ago.  one would be in profit at this point.  in 2015, there will be some difficult factors.  by may, there will be a huge difficulty jump as more mining farms get first dibs on HW with 0.2w/gh or less.  so again the difficulty skyrockets.  Then you will need to almost double your computing power by 2016 in order to prepare for the halving.

so can you make money now? yes, but you better start like in 2-3 weeks.  then you should run all the way until you break even, then pull the plug.  Recycle what you can then in sept-oct buy summer released miners. 

or you can do what others do.  Buy new miners, mine them for 1-3 months then sell them at a slight discount vs msrp with free shipping.
But that can complicate things on your taxes/accounting.

There are so many used miners on sale right now being dumped by people, who tried mining 6 months ago, you can get some cheap stuff and mine the crap out of it.
If you don't have enough cash you could sell the space for hosting, or start a legit cloud mining company.

legit cloud mining might be hard to sell, considering how jaded most people are about the concept due to the scammers in that space... but it certainly is a good idea.

[mavericklm]

with the price of $0.023 per KWh even s1 might be worth!  s3 is a good choice

Renting out rack space guarantees revenue, while mining put yourself at risk. Then again, no one is going to entrust their miners in your possession. Find a partner and co-mine is possibly most practical.

not sure why you think no one would trust someone else with their miners... there are a number of hosted mining companies around this town that seem to be doing well. just because you are paranoid and do not trust people, does not mean you speak for the whole.

[Dalkore]

That seems like a good setup and you are close to us as well.  If you want to get into mining, this is a decent start.   Unless that ventilation system has cooling, you might find it tough to run on air cooling during the summer (as you know).

I guess that depends just how much air cooling he has in relation to the 800A. If its a facility that's ready for 3400A then there'd be plenty of headroom.

Good post.  I also think finding hardware will be more difficult  in the  future as Most of the newer machines  Being made Now are meant for commercial-industrial deployment .
