Really!! How much speech You have to say for something that is achieved in one click.
It is not necessary to support your speech (story, OP), or your experience, quite some time ago on this same board an account appeared with a story similar to yours, but in that story the person who received "the speech" was scammed.
So, something he must have done himself ( You Friend), the supposed trust of friendship ended in fraud, the Friend giving him all the information, then stole all his assets, a decent amount of btc.
So this type of story should not be supported, it is not the way to lead people by the hands as if they were children, it is more difficult to open a traditional bank account than to have a bitcoin address and a wallet.
Don't be skeptical about the story, besides @OP can always advice his friend to change or modify security information according to his friend's likings. Sometimes people are too scared of touching anything especially if it is his first time, so the friend intend to ask for a guidance and spoon feed him if possible so that he can escape the nervousness and fright feeling.
It is easier to say when we are knowledgeable about technical stuff but some people aren't like us . So I believe it is a normal cause for someone who is asking for a guidance to tell everything besides, trust had been established between the two. So we cannot avoid the information telling part.
I believe it would be better if @OP will remind his friend to change the security if he is able to understand all the needed stuff in Bitcoin buying, keeping, and holding.
