almost all people who hold may be like you by getting a loss on their assets. but they still believe and enjoy it. indeed the current loss is very pronounced but you better focus on the work to forget about the loss
Forgetting the losses you have during market crash may take time but if i have to choose between moving on while i suffered a loss of my capital than suffering a loss due to selling it at a losing price, i would rather choose the former because i know, somehow, these crypto assets that i have will grow in the right time.
If you are long-term you will definitely not lose 50%,
because the future of crypto money is still good and long
