I bought bitcoin when it was around $14,500 in January and I am still holding because I am not discouraged. I have great hope that bitcoin is going to increase in price and volume in some years to come.
I admire your courage ti hold even price drips morethan a half from where you bought it. I felt lucky since I bought bitcoin when it was 8k$ and same as you I'm confident to hold and wait for bitcoin to bounce back even if it takes years.
