The futures on Bitmex go out less than a year, and on CME until Dec 2022.

I very much doubt they'll hedge with futures - I'd assume they just sell the crypto as soon as they have it. They might put on a position in a future for the short period of time between agreeing on a price and getting paid.

And of course the house will be denominated in USD. So, bottom line, not much more than a marketing gimmick.

ETA: And perpetual futures are basically just spot, with financing baked into a funding rate (which is positive or negative depending on demand, but unpredictable ex ante, and as such does not solve your problem).

It sounds like a fixed term future written by the lender directly may be a better option, I would not expect a large lender to actually trade futures Kraken/Coinbase.

Agreed it is a gimmick, I would imagine everything will be in fiat except at the time of each payment, when the instantaneous crypto value will be credited.
