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.
You are correct. Altcoin is not an investment people need to run into and just accept anyone that is being recommended by friends. There are lots of altcoins in the market and many are not legit, it is important to make your own research and not to rely so much in investing altcoins because they are not reliable to invest. Altcoins are project that you don't need to invest a good amount but the money you can easily afford to lose .
