Holding is for patient investors. Bitcoin keeps playing with investors emotions regularly and each time it tries to making a move up it keeps going dip.
Emotion is very dangerous for Trader and for investors, if someone is Emotional for his investment, if he think that my buying price was $10 and now price has $9 how can i do, i lost my money, then they sell their coin with low price, it is actually panic sell and for every investors Patient must Need.
Well, if you can't be patient and is always affected everytime there is dips happening, then better stay out from crypto. Otherwise, you will only regret why you had invested it in the first place because you only end up panic selling and lose a huge amount.
However, being patient in crypto brings a lot of advantages. Meaning, if you can simply hodl for long, then the bigger profits await for you. I still believe investing in an amount you can afford to lose is definitely helpful as it guide you to diversify your investments so you won't be losing in just a single time.
