oh boy that is a long list and I think you are correct about being over diversified!
how do you even keep track of all these coins? I personally find it impossible to do so, and prefer a handful of them just to be able to fully observe the changes and the news regarding all of them for some more precision.
from your list I don't know most of them because I have either never bought any or have done it in a very short period of time like buying in the morning and selling before noon
in the list I can say ETH seems to be on the pumping rise but I still consider it a highly risky investment.
also List has been rising very well so if you caught it early one you are in a good profit.
Doge coin rise seems to have ended, you should have gotten out 2 days ago.
ripple rise has ended about a month ago and I am surprised you even have it in your list!
byteball is a big no for me because of the way it has been distributed and the large supply of it.
NEM seems to be good but I have no investment in it at the moment.
Monero seems to be a more stable coin with less wild rises and falls so I consider it a part of an investment
Moon and RDD have been super profitable but they are at the end of their lines.
don't know much about the rest as I said above.
