Hey guys/gals(if any), shipping of the Neppy's is nearing ever so closely..has anyone done the mining calculations? one of my friends has 4 Neppy's incoming batch 2(order #180XX), he is pretty upset now because after doing his mining calculations he told me he would be lucky to mine 30BTC by Dec 2014 with all 4 Neps hashing away, is this true Huh

? can anyone elaborate with possibly some calculations from more seasoned mining veterans?

~Thanks

According to http://www.bitcoinx.com/profit/, as a Batch 2 customer, I expect to nearly pay for my original Neptune unit by the end of year including power costs. My profit will be found in 5 months of mining with the second unit, and in selling the used units at a greatly reduced rate when I'm done with them.

Of course, any predictions beyond a couple months are difficult to make with accuracy. And as with most investments such as stocks etc., "past performance is not indicative of future earnings". No way to be sure of anything.

I don't know what is "decline rate per year" in this online calculator. try this one: https://bitcoinwisdom.com/bitcoin/calculator

And the next difficulty adjustment is from 90P to 130P!
