My favorite altcoins were Doge (very good community), and Liteocin, both are dead now. Today the altcoin market has became unstable and scammy so i prefer to keep it in Bitcoin.
Might be checked CBX too mate, road plan and devs working right now, also open a signature campaign and a 30% bonus if purchasing it from cryptopia, making it possible to boom this year and cbx is not a new alt it has a strong foundation and have good dev reputation you can check it up and see the difference.
