Where is your list or link? Seems missing on your post. For now, I am not really holding altcoins hoping that one day it will give me huge returns. I am still sticking to bitcoin. Whatever tokens I had, I converted already to btc. Because for me, btc will stay in the market while most of those altcoins will die and perish. A lot of them will be abandoned. So the assurance of getting huge returns will just be a dream. I really don't trust holding altcoins for long time. Just my opinion though.
