Once-in-a-Lifetime Chance? Would You Go All In If Panic Strikes Again?

Ray Dalio recently warned that people are largely overlooking deeper forces driving almost everything—including tariffs. This sort of breakdown occurs only about once in a lifetime, but it has happened many times in history under similar unsustainable conditions. A WSB user posted: "I all-in'd and held $400K in UVIX for 6 months. I finally sold." Is the market at a once-in-a-lifetime moment? If market collapse occurs—would you go all in like this user did?
