Those who acquired bitcoin in early days got larger share in less price. Later when there are very less bitcoins left to be mined and prices are astronomically high, it will be hard to acquire even fractions of bitcoins. Where is equality concept associated with bitcoin then ?
Well, you are getting the whole concept of equality that Bitcoin creates wrong my dear.
Bitcoin supports equality not in how much bitcoins you are able to acquire, but in the sense that you are absolutely as free as the other user is to acquire as much bitcoin as you can afford, being the among the first sets of people to discover and buy lots of bitcoin at a cheap rates is only but an advantage, a self privilege which can happen to anyone including you if you were lucky enough.
It is only in bitcoin that you have the equal rights with the government of a country to even hold much more bitcoin than the government does as long as you can afford it, or you can choose to hold exactly the same number of bitcoins the US government holds if you have enough money to buy that much, no body will question you, it is just you and your bitcoin sitting in your bitcoin wallet.
This is the financial equality that Bitcoin creates, it's only in bitcoin can you own money even more than the government and they won't invite you for questioning.
