It's obvious that I should research each coin I'm planning on investing in, but as I am just a newbie and there are tons of relevent coins to look at (not to mention the whole crypto world and tech that I should catch up to) I want to devise a system so I won't get cluttered with less relevent info (which is bascally a huge excel table containing all the relevent data).
So my question is which information do you look into when searching a new coin, and which info is more relevent for later comparison between coins?

P.S
I'll gladly take research sources if you have something specific to mention.
