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 ?
If you have to pay 25% import tax you are automatically disqualified from mining, sorry I had to break the news to you. And yes many people have free psus/cables but you can always buy cheap server psus for $25/kw.
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
If you've been following the difficulty you would know that the growth rate is slowing down not increasing and it's less than 15% average. The low btc rate will only add to the slowing.
Even in your unrealistic scenario where difficulty growth stays constant at 15% you can still ROI because the actual price of the 14TH is clearly 15btc not 23btc.
dude, i can't belive you have so much activity and still know nothing.it's either you play dumb or ?are you that dumb ?it's not just 14 BTC, you have to add import tax, psu costs,maintanance, cables, everything else !
