Interesting as BitCoin proponents complain about Bankers greed and how 1% own a huge percentage of the wealth. It seems that a really small percentage of addresses owns most of the BitCoin wealth. And these addresses might be owned by even less people.
Compare the distribution of global wealth, or American wealth. And note that we can expect the distribution to gradually get more equal (as indeed it has been all the time) as early adopters slowly sell out and diversify their holdings.
It should be expected that any changes/disturbances in the financial system (including large scale adoption of Bitcoin) will involve some losses for the common person, while a few people will find a way to make a huge profit from exploiting everyone else in this change process.
