For any “meaningful” duration I strongly disagree with 1-3 … and bitcoin makes 5 obsolete because bonds won’t be generating 30%+ annual coupon rates. Bitcoin *replaces* bonds.

The only useful “bitcoin bond” duration would be less than 4-years to manage “short-term” volatility. And most bond buyers doing any volume are not max bidding short-duration paper. And those with a mandate to “buy bonds” aren’t touching bitcoin-backed bonds right now and by the time they get their mandates, bitcoin is already gonna have disrupted bond markets.
