I remembered that not so long ago I wrote a guide to cryptocurrency and blockchain. I was trying to keep it simple and plain, so even your grandma can understand it, hopefully.
So is twitter account @JustTechGuy actually you or not?
I don't think grandmas or grandpas can read 16 pages of document like this and learn much from this, but I could be totally wrong

Few things I would do to address criticism you received in forum from other members, maybe add source links for text you used or copied and place it on the bottom pages, most of page 16 is blank anyway.
I would focus on Bitcoin first, instead of adding altcoins in mix that will just confuse grandmas even more, and take some time to make updates and simplify it as much as possible.
