You bring up interesting points, one being silver. Silver has been a method of currency for a very long time. It has stood the test of times. No, it can not be transferred at the speed of light but it doesnt neeed electricity or any electronic devices either to buy goods with. Silver is just not appealing to investors at the moment because it is not a quick profit maker. But silver is in high demand in the industrial field believe it or not. So it wouldn't take but a few major events to unfold in the world and silver would go through the roof. But I'm like you, I'm no psychic either.
Outstanding response and very true! I dont think people realize how much silver is actually used in the industrial world. Silver is a very essential precious metal that shouldn't be taken for granted.
