I think everyone loss money their beginning of trading life. Eventually by your experience you will get knowledge. If you buy high you have to hold the coin until price go high.It is my way, I never sell without any profit.
I have same experience that you have faced recently, but I am holding them . Because it is a good project.
Everyone loss their money especially if they're newbie its a normal it depends on your experiences, you must have knowledge to overcome it soon without lossing just trust on yourself
