Leaving crypto passwords to my parents in case I get killed (cops in Colombia are killing us protesters). How do I explain to them in a simple way what they should do with it?

Hi!

It's not much what I hold, just a couple dozen XRP, ADA and a couple of dollars in ETH. If something happens to me, it may help them in the long term, I hope.

But I've actually come to this situation where I don't know how to explain to them what to do with it. I plan to create a crypto wallet in Metamask and leaving them the pass phrase in a letter. Sadly I can't talk to them about this because they usually think I'm going to my GFs and not the streets to protest (it's my duty) I don't want to leave them worried so I never tell them…

Is there any resource that can explain older people the basics of crypto, its potencial value and the basics for handling a wallet?

Thanks a lot.

Edit: to those saying people here shouldn't go out and "commit crimes" to not get killed, police is literally shooting students in the street for simply lighting candles in honor of those that have been killed by them. Get your facts straight please, and I really hope you never get to see this kind of human suffering In your country.
