I've been mining with SP Tech equipment since the SP10 rolled out.  Though BTCS/Spondoolies best get the SP50's fired up soon to ever be profitable against the competition.

 "BitFury derives sustainable advantage through its custom-made application-specific integrated circuits (ASICs), optimized to achieve the lowest power consumption coupled with the highest processing metrics – the parameters that drive mining margins. BitFury successfully delivered several prior generations of silicon and has a roadmap to at least double performance-per-watt every 6-12 months."

It makes me wonder what the mining industry will look like over the next ten years.  How "decentralized" will it truly be?
