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.
