Why goat my dear fellow, it's wild speculation, implication is in the eye of the beholder.
Well, the chart does imply a couple of things, amoth others the following.
The mining network will consume more power than a medium sized country.
The technology will still not be widely used, even at those price levels, otherwise it would have stabilzed with a high volume.
So, thats what you believe?
Why on earth does the mining have to use more power than a medium size country as the price rises?
