To clarify - I said crysis not in terms of "lack of money" in crypto-sphere. It was about the crysis of ideas - in my opinion, at the current moment we are stuck on the certain point with mass-energy-mining.
I full agree that P-o-c mining is looking far more interesting than energy-based one. Also it may be beneficial in terms of storing data - am I right? Or p-o-c mining considers consumption of all disc space?
Ok, so for the "crysis of ideas" I completely agree.
PoC simply consumes as much disk space as you assign to it.
On the other hand people are greedy and so today with e.g. Burst mining, you have to think in Terabytes or tens of Terabytes of miner size.
(Has a nice side effect - your view on hard disk capacity changes radically. I basically threw my 250GB hard drives away in light of as-energy-efficient 10TB drives)
Still, at the moment mining Burst is not profitable, the coin is way too cheap. I was just triggered by the term "energy mining", because IMO - in the long term - we need something that is by orders of magnitude more energy efficient than PoW and PoS cannot be it (see the fairness aspect and the irreversibility of a 51% attack). So for the moment I do not see anything else but PoC to provide that long term perspective.
