Yes, of course, I used to think that trading is a very easy thing. But when I started trading, I realized that there are hundreds of things that I and you have to keep in mind all the time. Because of a small mistake, you have to face big losses.
You think it is easy because you never know it well. Sure, it is quite complicated when you have tried to use it. Trading is a complex matter, it requires analysis and even a research. That's why we must have good knowledge first before we start trading. People sometime use demo-trading to get a deeper understanding. So it can be one of the way to make it easier, we use a demo-trading before we start a real trading. This can lessen the chance of losses.
Having knowledge when it comes to trading would be a good thing, but there are some things in trading where you will only learn it through experience. One example is handling your emotion. The more you trade, the more you can control your experience.
Trading really is a complex thing if you're a newbie, but the more you have experience in it, combine it with the knowledge that you have and you will become better and better. Demo-trading might work for some, but for me it will not because it will not teach you how to control your emotions. You will only learn to control it if you're using your own money. Have tried it, and it didn't work for me.
At the end of the day, if you're afraid of risk, don't trade at all. If you're afraid of losing money, don't trade, but if you're willing to lose, and willing to learn then try it.
