Ok, update. He didn't lose the BTC or get scammed. I had to spend some time trying to understand what happened and what he did. Turns out my Dad just didn't understand how to get to BTC holdings section within the app to see where his coins are. Then he misinterpreted the +/- differential and how to read the #s in the BTC section. I don't blame him bc the UX/UI in cashapp is kind of confusing esp for 80 year olds. All good though. Phew.
