Pretty crazy how difficulty is almost 200B and a year ago it was only 48B.
Well price was under 250 and the s-5 did .51 watts a gh.
So depending on the exact day to compare to about a year we are close to even.
I am on my iPad which sucks to,do a direct comparison .
I will go on the Mac mini and do Jan 1 feb 1 Mar 1 apr 1 May 1 2015
Dec 30 2014 diff = 40.6 price 317
Jan 27 2015 diff = 41.2 price 255
Feb 22 2015 diff = 46.6 price 237
Mar 22 2015 diff = 46.7 price 269
May 03 2015 diff = 47.6 price 240
May 31 2015 diff = 47.5 price 230
today diff is 194 price is 461
So compare us to May 31 2x the price so take the diff of 194 make it 97
and a top notch s-7 with a plat psu will do .25 watts a gh that is ½ the s-5 so 97/2 = 48.5
So an adjusted diff for now = 48.5 as compared to 47.5 the may 31st date of 2015.
So we are about an exact tie if you have an s-7 upgrade from the s-5.
Of course the ½ ing is around the corner so a shake up is coming
