Topic: Antminer S3 - Profit is Impossible - page 5. (Read 20101 times)
@DrG, KNC was just on time actually (Q1 or Q2).
May someone explain their rationale for investing in Antminer S3? Maybe something I missed?
Building up a hoard of aluminum, as long as I break even I will become a billionaire from all this aluminum, just watch me!
It isn't and every one of you posting this is wrong.
I have bought batch one S3's
I will profit with them
If you can't I don't really know what to say.

S1 owners like phillip (see above) took a chance and got lucky due to KNC, BFL, BA and others delivering late. I have free electricity and I was still skeptical about ROI. Considering all that late stuff is now delivering, I'll make a 1BTC bet with you that your S3 won't ROI it's BTC costs. With the 25% jump this last period it's going to get nasty pretty quick.

That....doesn't make sense. 478Gh/s at 360 watts is either profitable for you or it isn't. Having other devices mining as well doesn't contribute to the ROI of THIS device anymore than finding a hundred dollar bill laying on the ground does.
so i have 3 s-1's i made about 100 usd on them. they are undervolted-clocked 420 gh 560 watts.
if i sell them on ebay for 500 as a set of three . it is the best price anyone sells a 3 pack for.
some buyer grabs them and is happy for the good price. as he has free power.
i take the 500 usd and buy an s-3.. win win for all

I think partially you have to take into consideration that miners might be upgrading their equipment (swapping out S1's for S3's) as part of a larger farm contributing to more TH/s to maintain the increase in difficulty and driving down GH/s per watt for a farm. I would agree that a single S3 is not going to get you to profitability unless you have a farm that already paid for itself mining in contribution for ROI towards the purchase price for it.
The miners today aren't powerful enough to get ahead of the difficulty at a low enough price per gh/s to make a return. You need like 6TH/s at 1000w for around $1200, which I don't see happening anytime soon.

the reason these miners are sold so quickly is because of new miners. Every new miner heard of the succes of the s1 and when they hear the new s3 is announced they immediately jump in. As you said, no rational miner will buy this.
A good calculator for mining:

Play with these inputs and you'll realize that it's almost impossible ever to break even.
I managed to make a profit of 0.65 BTC only by using some very strong assumptions:
Price = 0.75 BTC (I.e. no VAT/customs, free PSU)
Electricity only $0.10/kWh
Only 10% difficulty increment
It implies that no EU resident will ever be able to make a profit. If you live in some parts of the US, you might profit marginally, but not worthwhile given the risk of hardware failure.
