My advice, don't give out advice. Or at the very least tell them they are better off not investing, you won't be blamed if there is a bigger correction.
I just think that it's better to give his relatives some ideas about crypto, not totally advising on what particular coins to invest to.
Per experience, most of the coins in the top 20 ranking appreciate in value overtime and if you hold into it i think we still profit though it will take some time but at least it is still a gain, this should be emphasized to someone seeking advises about cryptocurrency.
It is a need for them to understand clearly what will happen next and never give them the assurance that everything will be fine and works totally a 100% easy return.
If someone will ask me like that, I would say
"just visit this site first, do the study, and just come back to me when you think you are ready enough to lose". We never have to give them we will get money and have a quick return because it will get back to us and get angry once they fail.
That is very important for them to understand the risk and they should have the knowledge first before trying to help them, that could be fair maybe.
But, I don't want to encourage them to start now even they like it.
