Theoryreliable yes it could be a good idea with a guidelines of options for storing crypto. It should describe the risk of each option. I am quite sure you know what to do, but for newbies it is very different from what they know.
I think most of us has one or more hardware wallets for storage and most will consider that as safe enough.
Hot wallets on a PC is also used by more and then just leaving crypto on exchanges is also used.
I would certainly recommend only to have pennies on exchanges.
