I think that the best coins for investment now are litecoin and dash. I mean in them a big progress. I am sure that soon they will be the best altcoins.
indeed the coin that you suggest is good. I personally have often made a profit from BTC and ETH in investment so I prefer to invest in ETH and BTC because both have given me more trust in me, even everyone knows that BTC is a very good coin and can be trusted for the long term.
