Even the majority of exchange sites have been creating a guide to the new users to understand how crypto works and that's even a complete guide and i think your idea is not a good idea. I just try to imagine how you can compete with an active and popular exchange site.
If you don't wanna need to know deep about crypto and then you just try to know the basic like send, receive and store. that's enough for a newbie.
crypto is not a difficult thing like what you have explained. If someone wanna know and just read thousands article on internet about that.
