While trading demo the person may not put much effort instead will have that mindset that it's only demo therefore has nothing to lose from the trade but with live account the trader will be extremely cautious.
Testing the waters on a live account with small capital will give you an experience that'll have more exciting but traders shouldn't underestimate demo accounts as they're there for a reason. We should use demo to practice all our trading strategies and make our skills to be perfect before going lives. Losing a trade can motivate you but not everybody has the toughest skin to take losses and turn them into profits. Some traders lose their self confidence after they lost some trade therefore before putting yourself out in the real market, we should have had enough practice in the demo account to make our prediction to be more accurate and less of assumptions.
That's right, trading is difficult without proper practice as we all know that trading is more risky here own skill is more effective. If the market is not practiced well there will be risk in all trading. Many people think that demo trade is simple and very easy to make profit. But it is not. The real thing is that you are given a lot of capital in demo trade, so that you can trade well for a long time. Then again because it is not your dollar you do not become emotional, so you can trade pressure free. And you can not withdraw this profit because there is no greed and work so you can profit.
