I got into the bitcoin again last year after losing all my 4.5 bitcoins to ponzi schemes early last year. I bought in bitcoin again at $20k. Now bitcoin is $6k+. I'm regretting my actions. 
This is really hard for you because nobody is confident that bitcoin will go up to that point again, and the way for you can be to lose if you will sell now or to wait, if you have an ability to.
