I will give you a list of brand new or low cost, that on my opinion everybody need to hodl in 2018
they are:
UTN
ETN
IOTA
NXT
If you have oportunities to invest big amounts I recommend
ETH
LTC
BTC
NEO
IOTA
RIPPLE
MONERO
(classic ones)

good luck
everyone is mentioning eth but is this still a good entry point? at approx $1000??
