If I were you, I wouldn't place so much alt like that in my portfolio. The biggest losses experienced by investors in highly volatile times are from alts. Who still remembers the 2018 market crash which was led by altcoins with each altcoin giving around -85% to - 90% losses in value. Also most of the alts you mentioned are the lesser known. Lesser known are prone to dumps that coins everyone is talking about/actively trading.
yeah exactly, I have shared only 7% of my portfolio to such high risk high reward alts so I wouldn't lose that much just in case some real bad stuff happens.
And I personally don't see situation when you want to invest a lot in them - if you're low on funds, you don't want to risk 'em all, if you're extremely rich than most of your investments should be on safe haven
