Guys,
So far nobody mentioned some major (security) flaw in PoS coins.
Because the security flaws of PoS are not more serious than these in PoW coins but the truth must be kept secret.
Check this FUD attempt at PoS. I like how user nexern weighed in there with very simple but undeniable logic
to follow your crude 'pico-probabillity-attack-vectors' on pos, here is a crude pow one for you. just imagine that
for whatever reason, the power-lines to the three chinese mining-warehouses randomly gets broken. i guess in this
case the attack would be much cheaper, perhaps close to free compared to pos and as said, just out of the dark
without any chance or sign to prevent it. this is impossible with pos.
it's all about probabilities. N@S attack probability and odds of success? Cutting power lines to the three chinese mining-warehouses probability and odds of success? A sober analysis concludes the potential flaw of PoS is at least not more serious than the vulnerabilities of PoW mining centralization. Own both PoW and PoS, don't be an irrational supremacist.
