When we compare Bitcoin with the best, most used fiat and most reliable currency in the world, the Us dollar it clear show that Bitcoin is on a different level to the Us dollar.
I want to know what differences you mean, so there is a lot of material for us to discuss here. Fiat is clearly different from bitcoin both in form and in the degree to which it retains value. The levels of the two are indeed different, but perhaps you should mention more specifically so that it is more focused for our discussion.
Let me show you why wealthy men like changpeng Zhao(cz), Brian Armstrong, Jed mc Caleb etc can hold billions in Bitcoin without being afraid.
And there are also many other people who hold bitcoin without fear and that is because they are able to see good long-term potential in bitcoin. Apart from that, they also have greater opportunities because their financial level is very stable and they are far more affluent to invest in bitcoin. The level of investment they make is different from other people because they have become rich people in the world, investment must be based on the level of someone's ability to be responsible.
