We can't stop these traders who feel confident to use high leverage, especially if they made a winning history from it. Since they have made it before and make profits, then expect that they will still take that high risk again thinking the same outcome will happen.
Obviously, using high leverage mostly create negative outcome for many traders. That is why making profits on your first attempt won't guarantee another, there are more cases of losing than seeing your money double or triple its amount. I don't encourage using high leverage, except for those born risk takers as they will often do everything to satisfy their urge.
futures trade is indeed incredible temptation, especially if in the beginning already experience getting big profit because using high leverage. At first maybe feel very easy to get money, but actually that is the trap because slowly we start addicted and want to open position continuously without thinking the risk anymore. we never know, the market movement very volatile and nobody know for sure, and once hitting a big loss, usually we become emotional want to hurry taking our losing money back. Unfortunately, the reality is not as beautiful as daydream, many fail to win back because if already trading using emotion, in the end even become more loss and completely run out. in the end futures trade with high leverage ended just like a gambler who lose their control.
