I submit that more traditional investments aren't based on reality either. Commodities are driven by perception as much as supply and demand. Oil is a prime example. Stocks? When prices shoot up are they backed by an equal increase in real value? Are they based on the value of the company in any asset increasing way? If a company went under would you get your investment back? No, you would not. What one trades in is perception, the "hype" of Apple for example.
It's clear you guys know very little about investing or economics.
There are two types of commodities, hard and soft commodities. Soft commodities are mainly food products, like coffee, orange juice, and wheat. This is obvious, the price is supported because people need to eat.
Hard commodities are mainly metals. The prices are supported because most of these metals have solid industrial applications. Supply and demand. Some of these metals are serve a dual purpose as an internationally accepted, government approved form of currency that has been in use for thousands of years. You cannot buy a bag of rice with bitcoins in Morocco. But I bet you the guy would take gold.
Stop. I know what you're going to say. "One day, that guy will accept bitcoins!!" False. Do you want a currency that can be hacked? That has no central monetary authority and thus can be duplicated? That can be lost if your computer is broke? Gold/silver maintain their values as currency because they have been accepted for thousands of years. Governments or computer hackers cannot duplicate them infinitely. They can be put in your pocket. They will not erode. They can be buried, passed down, and are accepted everywhere because they're engrained in the culture of the entire world.
Deep breath. Let's go to stocks.
When you own stocks, you own a part of the company. That company has an intrinsic value. It's called "book value." To sum it up, it's how much money you'd get if you sold everything the company owns and converted it to cash. Skyscrapers, warehouses, trucks, computers, patents, trademarks, etc. You own something. So yes, it's very different than bitcoins.
There is a reason why a stock like Berkshire Hathaway or General Electric would never trade for $1 a share. They have "book value." And if they did trade for that price, someone would buy it up immediately and break the company up and resell it for a massive profit. It's how the market works.
If the company goes bankrupt, you, as a shareholder, still have a right to receive something, and often times you do. So you are wrong in that regard. Granted, shareholders are last in line to receive anything after lenders and bondholders. But yes, you can receive cash if the stock goes bankrupt.
Apple has value because it's a name that produces a product that people enjoy using. Furthermore, they have real estate, a valuable workforce (yes, employees can sometimes have value), patents for products people use, and many many other assets that make them valuable.
You guys need to take a business class or something.
