This conversation was not about banks when the comparison came up, and when I talk about long term value I'm not talking about bank reserves. (And even if you argue a stablecoin is like a bank, it's one with an utterly massive reserve ratio.)

If you're worried about short term value then you can use shorter term bonds if you want, whatever. It doesn't make a difference to the reason I brought it up in the first place, because either option is more stable than gold.
