As a newbie, I have little experience in choosing a promising altcoin and there must be some important thing that I don't know now in the process of choosing a altcoin. I want to stand on the shoulders of giants and I hope you can teach me something. Thank you.
to stand on the shoulders of giants, you can buy coins from the first 20 best coins in the coinmarketcap, these coins have really proven themselves as reliable, and I think that their price will only grow further
