I think, both. It redistribute wealth to those person who had engaged themselves here starting with nothing, and got to gain everything, then it make wealthy richer, since they already had a background in invesment and handling money for long term matters.
No, I think that is only making everyone richer. It is not the concept of whether it is helping someone from scratch or someone wealthy is using it for their own concerns. No this is not like it. Bitcoins are there for everyone. Every wealthy man is using for his earning, and every poor man is working on them to get a better income from bitcoins. So this is all about the hard work, chances are same.
