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.
