what actually happens why altcoin all red blush
this is a Q of a beginner

well i will tell you, the best part of a dip is to hold and buy more.
selling your tokens at dip will never help you and will just make you more miserable in the future. how did i say that ? well, you are not looking of future but the day now. cutting the holding will give you a headache soon and i am pretty sure of that. well, you are new and experience is the best teacher. so wait and be miserable.
And i do bet that most of us would really come into that state on where we do cut loss specially when we are still newbie into this field and i do agree on what you have said on here that experience is the best teacher which means on next encounter on these kind of situation we would eventually know on what are the things we should do which is to hold no matter what and doesnt tend to cut loss.
