So is it really solving the problem of inequality or Creating a new generation of people who hold power and shifting the inequality into a new form?( New Elites?)
If you are looking at Bitcoin from the angle of equality, you should look at it from the angle of equity, fairness and accessibility. Once you have your Bitcoin, you can use it as you like, like any other people (Rich or poor, Yankee or European etc) without any discrimination or rejection.
What you referred to is the reward for those who trusted Bitcoin when it was still doubtful, and if Bitcoin has enriched them, it doesn't matter (no partiality here). They are one of those who believed in it and made it have an early rise. This is a huge effort, trust and commitment that needs to be rewarded.
That is the way I see it. Has Bitcoin made them rich? Oh, Yes. Is the richness unjust? Heck No!
