There is just a slight difference compared to Bitcoin. In Bitcoin you got less than 1000 people holding more than 50% of all bitcoins.... None of the assets above have such an unequal distribution of wealth.
Not sure if you are just spreading FUD or you just don't know any better. You have 1,000 addresses holding 50% of the currently mined Bitcoin. MtGox for example is one of those addresses and they had at least at one point 220,000 registered users. That is just one example.
So what? All 220.000 users are dealing with one address? Even if what you said makes sense then there are 999 addresses left.
In any case it's not FUD or anything because bitcoin was never about even distribution.
