Trading and gambling are two different things entirely, I am not saying someone can not do both together or choose the one he likes but they are different. I use the money I can afford to gamble, but I still put more to trading because gambling is riskier.
I know they are different things. I'm just saying to the OP that he could just go and gamble his money instead of trading because if you don't learn it, it's like you are just gambling. It's a suggestion with what the OP could do if he doesn't study it.
It is good to manage leverage, the main cause of liquidation is the leverage used, many people are losing money and tired all because they are using leverage or using too much leverage. I started to trade future with 125x, I later know that even using 10x is too much and resulting to liquidation. There is nothing better than using 2x or not to leverage at all.
That's why it's better to understand and learn how it becomes like that and how it's being calculated. x125 is suicidal. x20 is okay, x10 is safe. That's just how I view it. As long as you have a very good spread and capital, you will be safe.
