I really was having this question in mind to ask if it will advisable for somebody who want to start up trying doing online investment and chooses trade as perfect for him or her.
Trading is not the same as investment, both are risky but trading is riskier. For anyone that wants to be a trader, my advice is to never depend on it, start small and use the amount of money that is lower than the amount of money that you can afford to lose to trade. If you continue to trade, you will know which step to take depending on how trading favours you. But just like gambling, never rely on trading, although trading is not gambling.
I totally agree with you, although some people are really mistaken for the two, most people think the both are two the same thing but forgetting it's a different thing, like the risks, time, energy and so on, trading requires all this while investing doesn't.
And also trading is not something you can easily predict just like gambling as you mentioned earlier, without patient, one can't really profit or cope with it, if they doesn't have enough patient to withstand.
