My grandfather lost his shirt in silver when the Hunt brothers lost theirs... I hate that bastard, he cost me my inheritance.
Bubbles. Jump on them instantly, the moment you notice them. Get out unreasonably early with big profits. Preferably years before the crash, but certainly months and months before the crash to avoid eventually losing big by getting your timing wrong. Or don’t play if you don’t own the casino.
Sorry your grandfather lost his money with the silver corner.
