You're right, emotion shouldn't be include in investments like this where there's high volatility.
This is also base on my experience and that's why though I see I've lost too much with the recent dip, I didn't panicked. I saw my mistakes before when the same scenario happened, the highest profits are coming through the holders and it's just the same like the past years. And I've learned from those moves now.
I agree with this because if you let your emotions affect your decisions in investing you could get into trouble. Many people always let their emotions affect their decision making like those who sell their coins out of panic and them regret the decision afterwards.
