I agree that a lot of people get rich because of bitcoin. But that is because they work hard to get rich. They totally believed in bitcoin and now made it to be a millionair for example. So if we all worked hard and did our best to believe in bitcoin i think that could make us rich aswell.
Everyone wants to become rich and dreaming to have a luxurious life and that will come true and with the help of bitcoin. Only we have to do is to trust in the pwer of bitcoin and other cryptocurrencies. Work hard on it and believe it will happen.
