My first was Ripple.. Still in love, but sold it few months back (I know, should not have done that). But now, still searching for that one new baby to start 2018 with.. I think I go with Iota, for the mean reason this coin doesn't add fees... Man-o-man.. If you see the rates of some coins! Anyways, just curious..
Ethereum
Think that's always a good choice :)
Verge and Bytecoin are my favorites for 2018.
Iota is great as well just cost more.
Steem on :)
