The problem with cash for gold schemes

Just a quick thought. If the economy ends up crashing, the dollar would not really be worth much. Gold and silver would still hold value though. Gold and silver would definitely be handy during an economic apocalypse. You could trade it for food and stuff. But what would happen if everybody sold their gold and silver to companies like Cash 4 Gold when times were hard (before things totally crashed)? Wouldn’t that just totally suck? No one would have much to barter with. But companies that bought everyone’s gold and silver would be living the high life. I’m not saying the sky is falling just yet, or that it will. I’m no expert on such matters. I’m just saying you might want to wait a while before selling all your old gold and silver jewelry. Otherwise you might end up having to sell your ass for sandwiches!
