everyone may differ in the meaning of rich. there are many people who think that the rich are those who are materially affluent, but there are also those who say that they are rich when they feel enough with their lives at that time. materially rich that is for those who can buy whatever he wants without thinking about money to buy it
For me my definition of rich are those early adopters of bitcoin, able to invest, to have a courage to hodl bitcoin for a long time and when the ATH of $60k above hit they become instantly millionaire or billionaire. I didn't mean that my definition of rich is an instant money but the bottom line of this is those rich people are those people who knows how to see the value of a certain thing, made a research about it and knowledgeable enough about things example like bitcoin and has a patience to wait.
