although many opinions say eth is the best coin, but I have added other coins namely neo and litecoin. maybe you can think of if the two coins can be one of the coins that have the potential to get big profits.
Litecoin already has a market that I think is the same as ethereum and bitcoin. Their market growth is also fairly good, especially what happened yesterday on litecoin experienced a high increase. it makes litecoin trade increase rapidly. for neo I think it requires more trade, or an increase in their platform so that they can compete with other platforms.
