Hi, long term minded newbie here. I've heard a lot of talk recently about peoples weariness of the dollars survivability in the coming year, causing people to shift to reliable assets like gold and silver. How would a hypothetical collapse of the dollar effect an index fund? I'd imagine uninvested currency would become near worthless, but would top us companies be able to survive such an event? Basically nervous if I should rethink my current low stakes investment strategy in this crazy time.
