I am not an investment experts but what I know is that altcoins investment is not what someone must pick for you, you need to do a deep research about the coins you are interested in and if you finds out that the coins have the potential of doing 10x of your returns on investment, you can go ahead an invest in the coins, it doesn't have to be one to two coins but as many as you can find that has the potential to give big ROI. When you don't do your own research and you take the suggested coins of friends, you have to be ready to bear the risk of losses too.
