60% annual income on investment sounds very low for scryptmining profits and low for btc mining profits for the next 12 months based on today's difficulty and reasonable assumptions on the future development of it unless you by that mean 160% ROI year 1, 60% return year 2,3,4....

But either way how did you come up with that number and how can you even estimate/guarantee any such returns that far into the future ??

Because right now we have approximate return on investment of 11% monthly, therefore considering distribution over the year according to difficulty raise and estimating expansion with new equipment we came to that number as one that can be guaranteed over the year of mining. Right now we mine 0.033 BTC a day with ASICs plus 0.008 a day on Doge, total of 0.041BTC a day. We purchased equipment from reseller in January for 1150$ each 50Ghash butterfly, 700$ block erupter and scrypt rig at almost 2000$, total 7300$. Right now we mine approx. 26$ a day (at 650$ BTC) less expenses, specially electrical bill. If difficulty was not an issue we would have mined over 9000 a year (if BTC stay at or over 650$ each), but we consider it and will replace all ASICs with or without an external investment. We have plans to purchase Cointerra 2 Thash and we expect 600 Ghash Monarch from Butterfly that was pre-ordered for 2138$ plus shipping. Also we will order new GPU for scrypt mining that costs 1100$ each for 1300 Khash We have buyers who will pay 950$ for each 50Ghash Butterfly and 380$ for block erupter. So we expand our operations regardless of any investment. We cannot guarantee anything beyond 1 year of mining, because BTC difficulty is unpredictable, its price too and Scrypt coins depend on BTC heavily. But it is in our interest to make this business profitable to profit from it ourselves, otherwise it would have been pointless.

Your current hardware you have is rather inefficient, it draws relatively large amount of watts in relation to it's produced GH/Mh, what usd/kwh electricity cost do you have.

I get the scryptmining you menton to be a loss for you at 0,13usd/kwh or higher at the moment you would probably be better off selling off those GPU's and get something more energyefficient maby some amd cards at around 3kh/w or nvdia's latest 750 TI with maxwell cores at 300kh/s 38.5w or even gridseeds scryptasics for 160usd(in quantitys of 200-1000 units)/350kh/s 7w

Those 260 gh/s sha256 miners still produce something but at 5w/GH there remaning productive lifetime if you pay anything for power will be rather short, i think you would be better off selling those for the prices you mentioned and at least get a KnCminer at 500+ GH instead, those really shouldent cost to much now(with 5995USD CoinTerra TerraMiner IV 1700GH(?) started to be delivered now and KnC's 9995USD 3000 GH machines coming soon), they were 5000-7000 usd back in oct/nov when they produced way more bitcoins than they do now.

As for the butterflylabs monarch(wasen't the monarchs originally inteneded to start beeing delivered in december ?), that company hasen't exactly been known for delivering in time, so one can only hope you get that one when they promised you to deliver it.

I appreciate your advice.
