That's really interesting. I remember that this JPMorgan CEO previously had always refused to recognize Bitcoin. He thought Bitcoin was a scam, a bubble.

Now his attitude has changed again—he also believes it's "better than the existing system."
Over these past few years, has the underlying logic of Bitcoin changed? No. It's just that the price has risen, and the scale has become so large that he can no longer ignore it.
Isn't this like how society judges a person? When you have nothing and you're still struggling, every decision you make is wrong. Your persistence is called stubbornness; your ideals are called daydreams; and all your actions still need improvement. Once you achieve success in a worldly sense, your past stubbornness turns into "decisive and resolute action," your rigidity turns into "long-termism."
