What exactly is the problem that you want to solve?

I'd start by properly orange pilling him. That is, he should convert his existing savings into bitcoin and understand that he will save in bitcoin in the future.

You will most likely be the only person paying in sats for a coffee in the near future (probably until the next bull market, with btc exchange rate 10x from here, likely 6-9 months after halving in 2024). Wallet of Satoshi is best for this situation.

Hat off to you, just got mine on 🤠

Thanks, guys, I'm still getting used to being here. :)
