BTC value has increased about 20% the last week, why did the price not drop by that percentage in btc?
I calculated over and over again, with kwh @ 0.27 and diff increase 15%, the S1 will never ever make the btc back you invested if I have to pay monthly the electricity from mined btc.
What did I wrong? Why should someone buy S1, at least in germany it's just stupid?
Last jump was 18%
I assumed 15% average in the future. If S1 does not pay at 15% it won't pay at 18%.
