I think $10 to $12 per MH/s is where we'll need to be by the 1st of Sept. if not sooner to even see a small ::)positive ROI.
this will definitely not happen. If you buy via preorder a Titan miner you have to pay 17,48$/MH/s + custom + VAT + shipping. Than you have to build up the miner by yourself & you have to put on top the electricity costs:
Example if you buy 1 Titan & live in Austria (where I am from):
Costs for titan: 6,995.00 $
Costs for custom 15%: 1,049.25 $
VAT on top of (titan+custom) 20%: 1,608,85 $
Electricity for 1 year (1200 W + 20% losses) & 0.27 $ per kWh: 1.20*1,2*24*365*0.27$ = 3.405.89 $
Total costs: 6995+1049+1608+3405 = 13,057,- $ + shipping 50$ = 13,107.- $
Price per MH is than: 13107/400 = 32.64 $/MH/s
And you even dont know when your Titan miner will start to mine. If I see how KNC treated their customers in the past, I am sure that they will again break their promise and they will not deliver in Q3 as announced. That means that your Hashpower will be even less worth if you wait another 3-6 month for "maybe" delivery of KNC Titan miner.
The earlier you start mining the better is it. The best way to start mining is always after a pricedrop like Genesis Mining had last week. That is the best entry point because you have the best price available in the market and the lowest possible difficulty as you can start immediately mining.
I am not a diviner - just resuming what happend in the past.
