I have a friend that is 75 years old. He was telling me how his friend is pushing 63 and has 2 jobs even working on weekends. I tried talking to him about bitcoin yesterday But he is cynical about it and he’s also very smart having been a lawyer most of his life. I sent him some sats and the white paper and had him scan the bitcoin.rocks QR so he can research for himself. What else can i do to make him understand the importance of Bitcoin??
