First off, What the hell. Why are you going to depend on your future spouse for your future stability? that's just belligerent and irresponsible on your part, and a little selfish too coz now you'd have to put the trouble of tending to yourself in the future to your husband/wife. That's just stupid.

But let me humor your question for a bit. Suppose you'd be given the chance to marry between someone who's fiat rich and someone who's cryptocurrency rich. I'd be practical and pick Fiat Rich. With its long-running stability, and the fact that Inflation works for the Rich, it just means that I'd get safety nets after safety nets, ensuring that I have a future to rely on. Which couldn't be said when it comes to cryptocurrency. The price of crypto is unstable, you could become cryptocurrency rich today and live in a cardboard box in abject poverty tomorrow, which doesn't happen in fiat rich people.
