The question is in general not just ada, but crypto overal. If several people has crypto as much as another millions of people, how it can be decentralized?
What would happen with crypto price if these at the top sell all them crypto?
AS perfect example is BTC, there are some guys who has million of btc, just imagine if they would sell them.
Another important question is fiat and btc, currently we know crypto value only in fiat, how we could measure crypto currency value without fiat currency? For exmaple fiat gone, what happens with crypto value? For a gold is not a problem, gold is the gold, silver is silver
