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.
choose the ones that are involved in blockchain dveolopment, like chainlink, those coins retunrns huge profits and a coins is its team or a massive community, ect
