Am I reading this right?
People are still buying Neptunes when KNC are at the brink of launching the 16 nanometer cloud and have stopped any & all support of previous products?
Amazing how people will buy machines BEFORE doing any research.
Your only hope is a BTC price hike to thousands of dollars before the diff jumps again. .... Good luck with that.
Worrying about a few Gigahashes is so futile... It's shear insanity!
Do the math... a Neptune purchased now will likely never ROI... ever. Not even with free electric.

Well, you know that no one is paying anywhere near $10,000 for a Neptune rig these days. So I'm not sure how you would know that they'll never ROI.

Lol, I can't believe I'm defending anyone who's still mining with KNC gear! But we shouldn't be surprised that people are continuing to mine with secondhand gear. I bet there are people still farting around with the first Avalons somewhere in the world.

well at $750 usd say with the additonal s shipping to you and free electric (which some users on here have with solar) it would take around 4.5 months to ROI with FREE ELECTRIC
and again if you had the proper PSU's from GPU days sitting about to use w/o that added expense.

using this calculator www.tradeblock.com

now I think? the Neptune draws at the wall about 2500w using that figure with 3.5TH I get the following and a 0% fee pool

at my rate of 12c per kwh I start losing money on the whole thing at 4.5 months ...goes downhill from there at least at these current prices

now both cases the 12c kwh and the free electric assumes you have 2 proper sized PSU's sitting about from the GPU days and that is not an extra expense to re-affirm that
likely 400 buck extra expense if you don't have such

so imho even at the free electric scenario .....imho you are better off just buying coin.....and hope for a price rise

and also the point that 16nm from the KNC splash in the mining universe is also likely coming here in the next couple months .....with their vow of wanting to own
40% of all bitcoin mining and transacitions fees as/if that applies by 2016.....well ...there is also that to consider

and again for myself I don't have free electric even if I did the added complication of where I am at I'd have to figure out a way to move that 2500w of 24/7 heat
and summer is coming........(got that issue with the Titans) a further consideration

nope...the boat has sailed...home mining is done.....but I take the point also that 750 for a used neppie now may be great fun ..and maybe under the right circumstances
you could ROI with free electric and such......but as a 'innovative strategy" for making BTC as of this date May 5th 2015..er no so much

if I get to the point I want to contribute to the BTC infrastructure I'll just run a BTC node for my 'good vibes' at an electric loss at that point in time..should it come.

but hey at least the guy is having fun at less then 1/10th the original price!
