That is definitely the solution to rate variability, but it doesn’t make sense economically. If you are borrowing money why would you also want to buy futures contracts, it would eat into your mortgage spending power when you can just trade in the Bitcoin, get a normal mortgage and probably far better rate, then buy at full buying power.

Thus you outline who benefits most from a mortgage in crypto -- someone who expects regular payment in fixed crypto in the future. For that person, their full buying power would be a crypto mortgage as they wouldn't lose buying power by hedging with futures against USD.

I have no idea who that person would be.
