PoS is broken. See these posts by gmaxwell (nullc).

Peercoin's PoS implementation has nothing to do with NXT's PoS implementation.

PoS may be broken in one system, but perfectly safe in another.

Just like PoW may be susceptible to 51% attack and successful double spending and selfish mining in Bitcoin, but not susceptible to those attacks in Myriadcoin due to its 5 independant PoW algos.

It is true there are different variations of PoS. None of them have been convincingly shown to be secure most especially not the versions used in 99% of the new PoS shitcoins that appear daily.
