That thought of yours count, BTC is generally for all the people, rich or poor, everyone is allowed and able to buy and sell bitcoins, imagine those people who were able to overcome poverty because of how Bitcoin continued to grow, most probably these people are more invested in Bitcoin after seeing such growth.
those who improve their economy with bitcoin, of course, are those who do believe and stick with bitcoin. Now bitcoin has turned many poor people into rich people. and that is the reason why there is always an increase in bitcoin adoption when its value drops.
everyone knows how the potential of bitcoin will grow again. so when it goes down, everyone who has already benefited from bitcoin will buy it back.
