My favorite coin for 2018 will be KCS (KuCoin). It's an exchange coin itself that pays out dividends daily to users that hold the coin. Depending on how much you hold, I started making $0.75 a day now I'm pushing close to $4 a day by just holding.
It's not a massive amount, but more volume means higher payouts. I'm making an extra $1,500/year currently by just holding a coin. Cannot help but enjoy that.
