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.

Well, you regret now. But if you wait long enough you will be saying oh I made some profit from this or if you wait longer, oh I made a fortune out of this.
So it is all in the waiting game really. Be patient.
