I urge you all to watch what is happening with vericoin before moving to PoS.
over the weekend mintpal was hacked 30% of vericoins (8M) were stolen.
the devs fearing 51% rolled back their blockchain in order to stop the theft.
this has created a huge controversy which can be seen in full detail on the vericoin thread (and the various a news articles)
they did this because if a thief gains 51% of a PoS coin they can have majority control of the coin forever because they can stake and very easily keep creating new coins.
this is not the same thing as a 51% PoW attack which only gives the attacker limited control while they hold 51% of the mining power.
PoS encourages hoarding and centralization of power more so than PoW...
the effects are amplified the smaller the coin.
I expect in the future we will see more PoS coins suffer from this vulnerability
I understand but emc2 need to do something to survive and the majority of people speaking wish for PoS. Will it change the way Emc2 is seen in the CC sphere, i don't know. Algo switch or switching to PoS doesn't do a thing if nobody knows it exist. People need to use it and right now everything is just a big speculative bubble.
What help emc2 prevent the kind of events that happened to VRC is that a lot of coins are already out, so harder for someone to steal the coins and get 51%. The volume is spread on 3 exchanges so i don't think it could happen to this coin but we never know.
