I know that lower margin and low leverage are also farther away from the liquidation price, so is it okay to set low margin and low leverage first to avoid losing if your strategy doesn't work, and then add if does the price follow your strategy? Is this also your strategy?
Actually it is better to have a start with this method if you're a beginner, firstly it help to cut loss and thereby reducing the extent at which you may loose your coins, but why some people choose this method probably is to participate on many Leverage positions within a day or short period of time, they are the the scalding and sometimes swing traders, but i think the best advice here is for you to discover your own best trading strategies.
The method is usually helpful if you are a regular trader, like maybe if it is your full time job. That way you would be a trader anyway and you should be good at it, if you are not good at it then why are you doing it as a full time job. This results with a situation where you would be making a profit a bit bigger and would allow you to profit a lot more.
This is how people approach leverage, it is a method where you know you should be right because it is your job and if you are right then why not make a bit more profit. Not everyone makes a profit, but that is the type of thinking they do before then join in. All others who do i,t do it because they have no idea.
by using a small leverage in order to have a small risk too, then this seems to be an exercise. but we should not be tempted to immediately use large leverage, because if we succeed with small leverage in a row, it will come to mind to use large leverage in the hope of getting big profits soon. the wrong way for things like this, because they have not been able to control their own psychology. even though it is patience that must be maintained until we understand market habits work
