Need help deterring elderly from a big mistake.

EDIT I’m not sure how to pin my own comment, or if I even can, so I’m gonna paste what I put here too ????

Alright back after a LOOONG lunch. The situation is handled, the money will be invested elsewhere, and I’m going to be helping her go down those avenues. Guy was shady af, and was less informed than I thought (and honestly hoped after doing all the research lol!) So yeah, he tried to spit jargon, he didn’t even fully understand it himself, and then tried to say XRP would be $11,986 soon! I told him he was full of it, showed him the numbers, and he left after a couple hours. Thank you so much everybody, I’m so grateful for all the help!

Ok so the title is wild I know, but I need some advice. I’m meeting with my grandma tomorrow, who is absolutely stuck in some weird Facebook crypto loop. She will not stop messaging me and my mother about investing in solely XRP. She refuses to look at anything else, and only wants XRP, because she swears a “good trustworthy Christian man” told her to buy it on Facebook. So I’m seeing her and her “good trustworthy Christian man” for lunch tomorrow, and evidently he’s a big crypto bro. Now I have a very rudimentary knowledge of crypto, but I’m worried I may be out of my depth if he starts throwing buzzwords around.

To summarize, I need some help arguing for her to invest in literally anything else, or nothing at all. So talking points that are anti XRP, or general crypto knowledge would be very helpful. She has already thrown lots of money away at random crap because people online, or people in the church have told her to. I’m just sick of seeing her waste her money on bad investments.

Mods I’m sorry, I don’t think I broke any of the rules, I just don’t know how else to phrase this ????
