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.
