Maybe I am thinking about it the wrong way. Please correct me if I am wrong here. My assumptions:
1. If Bitcoin becomes the medium of transaction the world over, as the world GDP increases, Bitcoin's value increases as the total number of Bitcoins is limited.
2. If I hold a large chunk of Bitcoins, I (and the successors to my fortune) don't have to do anything. As the overall wealth in the world increases, my wealth will increase proportionally. Inflation doesn't matter. New technologies don't matter. My share of the wealth remains more or less the same, except for small amounts I may sell to take care of expenses.
Current billionaires and companies are dependent on continuing to create new wealth to keep their share of the overall wealth in society. If they and their successors don't keep up by creating an equivalent share of the new wealth, their share will decrease.
So, this early mover advantage, is something the world has never seen before. Will everyone else who is not one of the early movers, especially among the current billionaires, companies and governments, let this happen?
