just dont go for LTC and ETH, and you will be ok 
maybe you should have a look at navcoin, they have a solid team and a very good project.
Is Navcoin a new project which launched recently . I can see that the price of the coins is almost 7k sat .Was there an ICO for the coin and if so what was the price then and what is the real potential of this coin.LTC and ETH are gone down and i dont know whether it will rise again in near future.maybe you should have a look at navcoin, they have a solid team and a very good project.
