How do you talk to your kids about bitcoin?

I have two kids, and the oldest is at the age to understand some of this stuff.

With any other parental discussion, I have no problem just jumping in and doing it.

But talking about bitcoin had unintended consequences. The thing I'm most concerned with is my kids may tell their friends we have crypto. It doesn't matter how much we have, if someone thinks we're crypto rich they may want to come take it.

I'm sure I can navigate this conversation like all the others, but I was curious if anyone else had the same concerns as me and managed to get through it.
