I've seen some estemints that the S1 would be reach its usefulness in November, "meaning it would cost more in power then it could make in a day" … Has anyone seen any estaminets on the S2 ? I know that it somewhat depends on what you pay per kilowatt , but thought there might be a ball park figure… The S2 is under volted in contrast to the S1 so per GHs it draws less power..
I am trying to figure out if and when Bitmain comes out with an upgrade kit to the new less power hungry chip would it be a good idea to make the change. I don't see the point in jumping right on the upgrade train if the S2 in its current state is making money and how far past ROI it is ..
One S2 1TH/s mine today 0.025BTC
1Kw/h x 24 = 24KW/h one day
the price of electricity for S2 one day in my sountry is 2,64 EUR
0.025BTC x 400EUR = 10EUR Profit 7.34 eur I currently have a 20 TH/s 20x7,34=
146 EURO profit in one day when I would sell BTC , but I do not sell BTC
I hope that the next level of difficulty give me a the same total profit, regardless one S2 miner will then have less of BTC.
Yesterday I bought a 5 AntminerS3 and DHL will bring me one Set of btcgarden-AM-V1 next week. Together 2.8 TH/s costs 4.25BTC . So I invested BTC in miner.
