wow the first idea is amazing and that would require a lot of work - but i'm ready to take on that challenge. A lot of the coins have very different technologies that are extremely difficult to compare, eg zcash and monero (cryptonote). I'll start building towards this!
I recently made a video on how to keep coins safe, do you want more in depth videos like that?
That would indeed require quite a lot of work ;-)
Personally I am very interested in this since I try to build a well balanced strategic cryptocurrency portfolio. For that I do similar research on the background trying to figure out which project to invest in within a certain area. I don't want to bet on all the privacy/anonimity focused coins for instance, just one or two. I do my research to decide on which.
If it would be valuable to you, just let me know how I could be of help in creating this type of content :-)
About keeping your coins safe, I will put my comments on what I think would be valuable additional videos below your post about this subject, to not clutter the comments here :-)
