I like many altcoins. I like Ethereum and Litecoin the most. One other good coin is NEO. I am currently holding many altcoins.NEO has the potential to give high returns to its investors. I think Ethereum can also give high returns like NEO but I like ethereum more than NEO. I am holding Ethereum, Litecoin, Ripple, ADA. I invested in Ethereum because of popularity of smart contracts and decentralized applications. Many Erc20 tokens are created and some of them can be useful. This gives more popularity and success to ethereum. I believe that due to great team Litecoin may still increase in price. The team behind Litecoin is good. I believe in Charlie Lee and I think he is a good leader. Ethereum has a strong leader too. Vitalik Buterin is a good programmer and leader.
