I heard that neo Is good to invest after Etherium but i dont realy know that token for me minexcoin is the best option to buy more and hold for long term because this coin has realy have good potential in the future.
Well in my own opinion, aside from bitcoins, you should only invest on altcoins because every time the price of bitcoins is dumping, ethereum is soon to grow back again so i prefer eth more than neo.
