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.
You czn cash out out anytime but to be able to get a profit you should cash out your bitcoin when it is in the highest price.
This is the perfect time for cashing out bitcoin since it is above 8000 dollars at present and there are maximum chances it will further increase in value. If you are really in need of money, you can cash out bitcoin right now but if you want to have big money, sell off bitcoin by the end of December because there are maximum chances that it will further increase in value.
