Posted this on AITA and got mostly YTA — curious what the Bitcoin community thinks

I posted a situation on AITA earlier and got a ton of YTA responses, so I wanted to hear from people who actually understand Bitcoin and the tech behind it. For context: (im a 15M and my cousin is 20M) I’m into Bitcoin on a small personal level. I’m not a trader, not trying to get rich quick, nothing like that. I’ve been learning for a while and have about $2k in a cold wallet that I just hold long‑term. My grandma is pretty curious about new technology. She’s asked me questions about Bitcoin before, and I thought it might be fun to show her how it works by sending her a tiny amount (like $20) from my own money, only if she wanted to try it. More like a hands‑on demo than “you should invest.” My cousin is extremely anti‑crypto and very anti‑capitalist. When he heard about this, he got upset and said I was “taking advantage of her” and “pushing risky investments on an old person,” even though she wouldn’t be spending anything and I wasn’t telling her to buy or invest. AITA basically agreed with him and said I was the asshole for even considering showing her how Bitcoin works. So I’m curious what this community thinks: Is it wrong to teach an older family member about Bitcoin if they’re interested, even if you’re using your own money and not encouraging them to invest? Genuinely want to hear the Bitcoin community’s perspective.
