NEO is a good altcoin that will grow soon. Beside it I would add onecoin, litecoin and PRL
NEO is the most rival of Ethereum on beating Bitcoin's market cap in the future.
NEO is fast, scalable and flexible so I am seeing brighter future of NEO together with Ethereum in the near future.
PRL is one of my best Altcoin because it do offer me higher opportunities that compelled me to go home and start over and invest into local businesses in my community.
