why bother pay 14.9 BTC for these when they can only produce like 9-10 BTC ?

So I take it you have a magic crystal ball too?

Mine says these can easily break even with cheap electricity.

lol, you are a joke

even with free electricity they won't ROI.remember they will start shipping in at least 2 weeks from now, you need to pay import tax in your country,and you also have to buy PSUs, cables etc.
you have all these for free ?

let's run a small simulation assuming everything will be in our favor, the small miner:

-only 15 % diff increase (which we all know will be much higher)
-14 TH/S
-free electricity

you will still be in a negative -7.7 BTC in more than 1 year from now on.after 1 year 14 th/s will be worthless

15% constant diff increase? 3'000 G difficulty in Oct 2015? Or 21'000 PH?
Let's take that by that time mining hardware will use 0.5 kWh/TH, and electricity at $0.1/kWh ...
Bitcoin has to be valued at $6000 just to cover this running costs. Nice Wink

That or if bitcoin stays at $385 like his totally realistic predictions suggest it would mean that all the hardware powering the network would have to be at least 0.025 w/gh if they expect 50% of daily revenue to be profit. (at $0.05/kwh)

I'm not entirely convinced we will see hardware 200 times more efficient than current gen hardware in only a year.
