How about cardano, iota, tron, nem, str, xrp, bcn, 0x, bts? Because those coins are less than $2, and if you check on the coinmarketcap, you can buy a lot of amount from each coin. I think that coin is very potential to increase higher in this year although at the first month until now, the price is at the lower price, it is possible to getting high again at the end of this year or in the next year.
