Bitcoin and S&P 500 were chatting in a bar. S&P 500 said proudly: "You know what? I've risen 60% in the past two years!" Bitcoin smiled and said, "That's good. But I've risen 220% in the same period." S&P 500 was a little unconvinced: "Huh, but my growth is more stable, not as ups and downs as yours." Bitcoin shrugged: "Yes, but excitement is fun, isn't it? And now there are ETFs to help me attract more fans!" 😂
