Guys,

So far nobody mentioned some major (security) flaw in PoS coins. If you create enough demand on a PoS coin, nobody will care about people with larger wallets. Let's face it - most of the people are with weak hands. Example: There is a cryptocurrency with 20M in supply, 1-2% yearly interest and a guy who invested 5-10 BTC to buy 25-50% of the entire currency @ the price of ~50-100 satoshi. If that currency becomes viral, then the price may be 1k satoshi or even 100k. Do you think this guy will hold all of his coins? He will most likely sell them, when he sees x5 - x10 profit. Then you have another guy who bought the coins of the first guy, but the price is now 500-1000 satoshi and he invested 25-50 BTC. The currency becomes even more viral and the price is now 5k satoshi. Second guy sells half of his coins with profit and holds the rest. After some time, price is now 10-15k satoshi. Second guy is out and there is a 3rd guy (whale), but with less % of the currency. I think you guys get my idea. Most of the people are here for the fiat money they can earn and they don't care about the technology and about how cryptocurrencies may be used in the real world. If you manage to make a cryptocurrency viral (were 10s and even 100s of thousands people are using it), then you will not worry about N@S problems and such, because at this point, there will be not 100-500 wallets, but 10s of thousands. You still can buy bigger % of the currency, but at this point you will need millions of $ for that. That's something, which only serious investor can do and serious investors are not f*cking with their investments.

But every time the coins are sold the number of wallets doing the staking increases. The more wallets staking, the safer the network.

There is no incentive to run a full node in BTC because you have a cost but no reward. But there is plenty of reward for PoS holders.

As far as I can tell, the only PoS coin that has gone wrong is Clams - so much is held by JustDice, who stake them, that the difficulty has gone through the roof and it's pointless any one else staking. But those types of flaws are easy to solve with some velocity in the coin, or limiting the ageing required to stake.
