Pure - unmitigated idiot.  '$15 Million worth of electricity'   Which of you morons believe that?  Even the article cited is largely dedicated to show that is complete bullshit.  Clearly, you are an incompetent fool who cannot perform even simple arithmetic.  Bitcoin mining takes about the same energy as it takes to make a few more tons of steel today.  A meaningless amount in comparison to the worlds demand for other crap.

Go back in your hole NXT promoters.  NXT only solves one problem - and that problem doesn't exist.  Green fools.
