Yup, that guy just earn a hundred million by just buying bitcoin, that is one of the reason why billionaires and governments are afraid of it, it can easily make people a millionaire or even a billionaire as you said. Without doing any job or without doing anything that millionaire became a billionaire just by simply waiting for its price to go up. Basically it can make people richer but it cannot make poor people rich and that is one thing that makes it unbalanced.
