Patience is indeed the key especially in this kind of market but bear in mind that not all the coins will have the same outcome if you hold them so you better choose those coins that are certain will give you a profit. Just like you, I've been holding some of my coins I found that the profit I will make right now if I sell them is quite small thus, I will hold it until I reach my target profit before selling. But anyway, congrats on your success, you deserve that profit especially you managed to hold it for 5 years.
