I am kinda new in this cryptocurrency and i wanted to buy some altcoins but i don't know which one, my friend said i should buy neo but i am not quite sure if it is a good coin or not.
NEO is very good potential I agree with your friend but I think there are many coins are more effective such as:-
ETH
Monero
Ripple
Dash
LTC
NXT
OMG
BCC
Walton
ETH Classic
