A lot of people say let the fiat people drown, suffer, and die. I don't think that's fair, most fiat people are your parents, uncles, aunts, cousins, relatives, etc. who have been alive for 20 to 50+ years who are working with the only system they've known their whole life, they're only operating with what they know. If they won't accept Bitcoin, or Monero, that's fine, most won't get it, be kind enough to build a I told you so pile for them to get cheap sats when they finally do understand. But in the meantime try telling them about goldbacks so at least their life savings don't lose value. There's always a way be patient, the network will heal itself in due time.
