Investing in new coins at this time is very risky. I'm investing in some altcoins because I believe Ethereum, EOS, Waves, Litecoin, Dash, Neo are the best coins, These coins have a strong and reliable team.
There are many potential altcoins in cryptos market, it depends on the way people get information as well as experience some coins in order that they themselves believe which potential coins are. Honestly each person has his own evaluation about coins. To me, as my knowledge as well as observation, the top five potential coins respectively is Ethereum,Litecoin,Cardano , Neo and Eos. I really have belief on these coins, especially ethereum, not only me but also many people in cryptos community draw attention on it.
