Should I change my small portfolio stocks

So I’m 20 years old and started out about 2 years ago opening a Schwab account during a great time to invest. I put $2000 into a general market blend, putting in roughly $75 every few months on average since then. My deposits along with the market rose my portfolio up to about $2700. I did some research and heard talk about $SQ a month ago and moved $300 from the index fund into $SQ and have been very happy with what has happened! Should I move some more money from my index fund into potentially great long-term stocks like $BABA and $MU or keep putting my money into the index fun?

Extremely high risk and lots of research is needed to protect your investment as well. That being said, ETH has a great entry point and is making a hell of a run right now
