not really related to the question i was looking for which is better between the two companys now Spoonies or Bitmain.
your answer can not be answered as you can not send any coin to bitmaintech so no one knows the answer.
my answer which was not the answer you are looking for is the correct answer for the most likely to roi of the current gear offered for sale.
If I was to buy I would buy the prisma tube super tube as first choice
Amazingly my second choice is an antminer s-3 on ebay which I can get for 261 after coupons.
my third choice is the sp20
my foruth choice is the bigger dragon miner 1.5th
my fifth choice is the unavailable s-4
if I could buy an s-4 I would order it as my third choice over the sp20
but since I can not buy a s-4 I can not anwer the question you are asking.
I can tell you I purchased an s-3 tonight on ebay. I paid the sell 300 and I got back 39 in coupons so I paid 261 for it. At 261 it is better fro me then the sp20 or the s-4
why?
I have a spot for it to be used as a space heater that will lower my heating cost quite a bit..
I can make it be quiet and still hash at 440gh.
I want the super tube most likely I will order it. Most likely I will never order a spondoolie as I can't get them to agree to my terms.
