Use margin in crypto trading is one of the mistake for newbie trader, and second mistake is did not use stop loss and greedy. Learning from previous trading mistake , we should be avoid greedy and create better trading plan. Become successfully trader need times and we should be pass alot of thing like loss, stress and others emotional, but by surpass it we will make our self become pro trader later.
This is funny lol, I remember when I was a newbie and I never knew anything called stop-loss as of then. I would usually start a long term trading with hopes that the market will go direction I have predicted and by the time I get carried away and return back everything is gone.
But after someone taught me how to do stop-loss I have been able to set trade and go out and once the market drops to the rate I stop-loss or take profit it withdraws.
