One image to explain: What exactly is a quantum attack, how it threatens Bitcoin, and how Bitcoin responds. This graphic was generated by GPT based on my previous content, merging it into a super clear explanatory image. No gibberish or typos at all—so useful. GPT-5.5 has not only significantly improved in coding and reasoning abilities but is also insanely fast, like it's on steroids. Spent the whole day playing with it, had so much fun. Highly recommend everyone to try it out for yourselves!
