stablecoin yields vs traditional savings and why most people still don’t get it

So I'm at christmas dinner right and my dad asks where I keep my emergency fund. I mention stablecoins earning 6-8% and this man looks at me like I just told him I invested in magic beans or something lol. Meanwhile hes been getting 0.4% at his bank for literally twenty years and never questioned it once.

Tried to explain that the yield comes from actual lending demand, people borrowing stables to trade with, not some sketchy ponzi thing. Could tell he wasnt buying it though. And honestly I get the skepticism because crypto has given people plenty of reasons not to trust anything in this space. But at some point the math is just the math? His money loses purchasing power every year guaranteed while mine at least has a fighting chance.

Anyone else just completely give up trying to explain this to family or is it just me
