The protocol itself? Nah. That's rock solid. What keeps me up at night is people not getting it. Leaving coins on exchanges. Thinking "I own Bitcoin" when they own an IOU. We've seen this movie before — it's called gold. The metal didn't fail. People just stopped holding it themselves. Paper promises replaced the real thing. Then confiscation. Then debasement. Bitcoin fixes this *only if people actually take custody*. That's the whole point. You can hold your own money. But if everyone's too lazy or scared to do it... we just rebuilt the system we were trying to escape. So yeah — not the code. The culture. That's what I watch.
