2 things that I found interesting in this article :
1/ '' the prospect of new supply halving has already helped drive bitcoin up over 50% this year, which should help ease the pain.''
True unless most of the small / medium miners gonna close the business by now
2/ '' they hope the number of bitcoin transactions will have grown sufficiently to mean that the small fees paid by users will make up enough of their income to smooth out the profit cut.''
This only thing will keep mining profitable after 4-8 years
I mean to say, with the Xbox One coming out at Peak Throughput of 1.31 TFLOPS and a relatively cheap price.. something could obviously be done with all that
