I don't have any grandma's left and my parents don't.  My Dad tried to bad mouth bitcoin and then stopped himself and asked if I had any, He stuttered and still tried to bad mouth it because one of his friends had lost bitcoin because he didn't protect his keys.  Someone staying on an exchange or losing their keys is not bitcoins fault, but in his old age, he doesn't like change.

I was flattered that he realized that I might have bitcoin. 

 He He. He knows what a dangerous woman you are. 😁 

 He thinks I'm crazy and clueless.  I think he's short sighted and unable to accept change.  Family get-togethers are interesting as my husband keeps kicking me under the table or giving me the "don't go there" back rub to keep me from discussing things that might cause a fight. 

 I got my stubborn genes from him. 

 Same. 😂 My dad is also as political as I am, and cutting edge on tech stuff. 

 He also loves to read and is a good writer.
