Note
I added point #3 as why PoS is MUCH less secure than PoW.
Basically this boils down to the same conceptual tradeoff as the post where I replied to ArticMine, in that allowing decentralized participating enables unbounded conditions (which is a flaw) but centralizing participation also leads to another set of flaws.
Crypto currency is flawed as a concept. Appears it can't work.
Completely decentralised, maybe it is (like FTL space travel). You could be 100% spot on, I'm not arguing that. However, maybe the notion of a completely decentralised currency is also flawed.
Since you genuninely seem to care for the common good, please consider what's more important to everyone: Perfection or improvement?
I could argue that the notion of value/power always leads to some centralisation or other. There is no technical fix to that, simply because: We have computers that can beat your computers.
On a
practical level for overall improvement, the question becomes what implementation keeps centralisation in check as much as desirable.
