You can't just start investing stocks if you have no idea how the stock market is ran, how interest rates affect prices, how the prices for stocks even come about. You will not make hardly any money at all if you just hop in. I can guarantee if your uncle really makes $10,000 a month, he either watches the t.v. a lot or he studies the stocks on the computer, and he already knows what everything is about.

If he doesn't do those, then I supremely doubt he makes that kind of money.

If you don't know anything about the stock market, you shouldn't invest. This isn't a fucking game. The smartest people in the world are all up in this. You can't just walk in and expect to be rich the following month.
