I just ask, do you have a deep knowledge of margin trading? Because if you suddenly come up with no idea or knowledge it is no wonder if you lose the margin trading. As far as I know, you won't get any benefit if you don have any deeper experience there.
Margin tradings are high risky but cross collateral margin is more risky than isolated margin. With isolated margin, you will only lose your collateral in that isolated position but with cross collateral margin, you will lose more because your collateral is cross, not isolated.
I've been here for a few years in crypto Trading I haven't tried margin trading yet because I know my capital will goes to nothing only, instead I do trade on spot most of the time.
Many warnings but many people feel interested in margin tradings because some successful traders show their big profit with margin tradings. It cause newbies, amateur traders to jump into margin tradings as successful traders did not warn newbie traders about risk, forced liquidations.
You made good decision by say no with margin tradings by the way.
