Cost of a bitcoin generated

Quote from Hoi:

a 50 TH machine would use 10,000 Watt (90 Amp/110V or 45 Amp/220V). This will make it impossible for the average Miner to participate in the Network (even if he can easily purchase such a beast). I see this as a huge problem (for 2015 and later) as the network should be as de-centralized as possible....(I don't think Satoshi had this in mind).

agreed, good point. ultimately a single unit will be capped by the outlet power limit (~1500W in US i think). People can just buy multiples and stack them together each with a separate power supply but physical space will limit such setup.

I am hopeful there will be many data centers spread out around the world to host those machines once the asic caps out, as oppose to a few large data centers which will pose a significant risk to bitcoin, as it is nothing without the backing of its network.
