Bill Gates and Warren Buffett and Elon Musk are two different kinds of people, although they are both rich. Bill Gates, we can call him "the ball guard", you see what he does with his wealth, whether it is to go to Africa to cure diseases or in the United States to enclose land to improve the soil environment, nothing but to their own power to delay or even improve the human on the earth has been on the verge of collapse of the living environment, to make the earth a better place. If you look at Elon Musk, we can call him a "ball pie", whether it's building cars or investing in Bitcoin, it's just a way for him to make money. He just wanted to amass the wealth to develop rocket technology so that he could aggressively push his plans to leave Earth and land on Mars. Musk has found that Bitcoin is the most efficient treasure bank in the history of mankind, and that by tying it to him, he can greatly advance his goal of landing on Mars, so he has put a strong stand on it. Bill Gates, on the other hand, believes that Bitcoin has no value for human beings. It can neither promote the development of science and technology nor improve the living environment of human beings. It only consumes a lot of resources, so he firmly stands on the bearish side. So they're opposites.
