Jeff Bezos' networth is 190 billion. Satoshi Nakamoto could be owning around 1 million Bitcoins. If 1 Bitcoin would cost more than $190,000 than his networth would be more than that of Jeff Bezos', assuming it won't change, for the sake of argument. There are other individuals who hold a lot of coins, but still much less than a million coins, so Bitcoin would need to cost millions of dolllars for them to become the richest person in the world.
Bitcoin and legal currency have one thing in common. They will not choose the rich and the poor. They can be used by anyone. Bitcoin is still in its infancy. Investing in Bitcoin and holding it for a long time will allow you to achieve wealth freedom. (The key point is still Are you rich in fiat currency). For those who are expected to realize the freedom of wealth, then accumulate your bitcoin amount little by little now and recharge your beliefs. This is the most effective way.
