Bitcoin Forum

I'm talking about btc miners ofcourse.

Also whats the lowest cost ones:
Electrically
usd per gh

Of course, everything is cheaper buying in bulk.

Stop. Read this https://bitcointalk.org/index.php?topic=504530.msg5557195#msg5557195 then continue asking questions.

Then check out my thread will help narrow down your selection of places to look for miners in bulk, which cuts through all the BS and just gives you a Thumbs Up or Thumbs Down on the various sellers of mining equipment.

Except bitcoin. And pretty much anything sold in an exchange. Unless someone finds a private deal with someone that wants to sell a lot of bitcoin at once.

Thanks ill make sure to take a look at this.

Okay so i looked through seen these:
easy2mine.com
iasicminer.com


Why are they do cheap? Is there something wrong with them. Okay lets put it this way what would  you say i drop 20,000-50,000 On best bang for my buck this would not be for resell it would be for a personal farm.

You are welcome.

Tread carefully down the mining road it is not for the faint of heart.

absolutely true need balls of steel when that coin prices starts dropping.... :o

How low will it go? ;D

No.

To be honest if you are going with that sort of volume you will need the space and you will need better efficient miners and some damn fine cooling. SPTech puts out the best units on the market currently in terms of density, ease of application but you will have to wait until mid to late October potentially. This is not a game to just drop a $100K USD at the problem and expect some great return. At this point you would be better off partnering with people and pooling a larger amount and getting the greatest possible discount on hardware you can manage.

This is the sort of thing you compete with now...

Are you thinking 20 mW or more?
Do you have millions?
Who are the members of your team?
Where will you locate?

This is the playing field... you want to jump in? Get your hip waders or maybe the floaty cause the waters get deep really fast.

MegaBigPower’s mining operation is divided between locations in Poland and the United States. In the USA, we have nearly two petahash of bitcoin mining set up in eastern Washington State. The location was chosen for its ready access to affordable, environmentally friendly power. Since 2013 the mine has grown steadily and, thanks to control of our entire supply chain, the rate of growth is increasing.

EXPERTISE

If you buy more then 10 S3 antminer, I believe they can give a discount. But don't expect a lot of discount unless you are odering 100+

If you buy in bulk, you will get them cheaper.
If you buy in bulk, you will loose less moner per device.
If you buy in bulk, you will loose in total more money then when you buy less.

Unless you have access to electricity costs a way below 10 dollar cent, preferable 5 dollar cent or less you will not ROI.

Yeah but what i see if this knowledge is basically kept secret, Ive noticed even with the the money to start all this up people tend to keep their info to them self's.

If anyone can tell me something real that can help me We are willing to pay for what needs to be done. From what i understand sooner or later if you ain't got a big network behind you its not going to be even worth mining anymore.   

While the percentage of difficulty increase is slowing down, the percentage of your electricity costs compared to your earnings is growing steadily.
A while ago, less than 5% of your earnings are spend to electricity.
BTC price was higher at that time and there was less hashrate.
If you use for example 15 dollar cent per kilowatt/hour and BTC price of 500 dollar and a 1 Terahash miner using 1 kilowatt/hour.
Your earnings are 0.02109 BTC a day. 0.02109*500 dollar=10.545 dollar a day.
Your electricity cost is 24*0.15=3.6
10.545-3.6=6.945 net profit a day.

3.6/0.10545=34,13940256045519 % Percentage of the electricity cost compared with earning.
You also need to factor in at what price you are buying the miner, if you can't factor in simple maths, you will never ROI like 90% of the miners.
You can't blame some miner become bigger and bigger or that they start earlier with mining.
There are lots of miners who started late, but can ROI, because of luck or they had access to cheap eectricity or they can do simple math.

If you have access to electricity cheaper than 10 dollar cent and really wants to start mining and wants to buy in bulk, I can act as a agent for you.
I am in good relation with a lot of manufacturers in China.

If you don't have access to cheap electricity, forget about it.

Correct. Unless you have an experienced team and enough money you shouldn't even bother.

The Bitfury 20 MW farms and those farms I posted from China below are the standard  or benchmark. The ones in China and Thailand that I know about are dirt cheap for hydro, cooling and buildings. Think big chicken coop and cheap coal or hydroelectric.

You can't compete with them as they are the same people producing and sometimes selling the miners and chips so their economies of scale per Gh/s is the best and certainly better than their own largest customers. The game you would need to play is working something on a large scale operation say with Spondoolies units and direct ship to a site you have already prepared. Get a bunch of people together and pool your 30K buy ins.

A lot less bothersome? Buy BTC or even some Altcoins and sell off when they peak and then build a farm.

This above.....electric rates of 6 cents per KWH or less,higher than that & nothing short of a miracle can get you ROI  ::)

No matter how cheap the miners are................................
