I suggest you go with Etherium because it's the best altcoin in the market, it has the highest market cap and trading volume among other altcoins which means your investments is secured because people do a lot of trading in the coins. But EOS and EOS are a decent coins too thats why they are in top 20 coins list in the market today. No matter what coins you will be choosing it will always on your trading style, because skills matters.
