I think the 6 coins you hold have the same high potential.
the coins you mentioned were very popular some time ago I'm sure they will lead their respective industries based on their ecosystem.
If I were you, I probably wouldn't sell it now unless it means I'll buy it back at a lower price if it's in a bearish condition like now.
the most important thing is asset management, if you want to sell between them, you can sell them if it means urgent because the coin has high potential. If you may know, what makes you want to sell among them?
