I was so nervous that when bitcoin price dropped to 6000$ I was scared to loose more and withdrew my coins only to regret later that it became 8000$.
Please help me with your advice /opinion.
That was a huge mistake you did but dont regret it too much almost all of trader have already been experience like that when they are newbie also so i think that was normal for you. The best thing you have to do now is take it as a lesson and dont do it again.
