I have never agreed that material-based marriage is not a marriage but a transaction, If there is another choice then I will choose to marry someone who is commensurate with me (who loves me for who I am).
However, of the two options above, I would prefer to marry a crypto rich rather than a fiat rich because I already know how big the value of crypto assets is, especially if my future partner has a lot of bitcoins, not satoshis.
It will not last long if the marriage is based on material things, where there will be conflict later when the finances are no longer stable and the wealth previously owned will become a demand.
When I have to choose between the two, on the contrary, I prefer FIAT rich people, where the results of their wealth are real and can be developed in various other businesses and one of them will be used as an investment asset in crypto.
That's obvious and of course vice versa, marriages won't last long if they rely solely on love without any material possessions to survive. In my opinion, both have an important role to play so that the marriage or family relationship can remain harmonious and run normally. It's true that if one of them gets married for the sole purpose of material things then there's probably something very likely to happen in the future, the life of their marriage won't last long and obviously if the material things eventually disappear then maybe divorce or separation could happen.
That's a pretty good choice, but I think it's just about a little bit of a difference, I think whether they're rich in fiat wealth or crypto wealth I don't think it's going to affect their lives that much, and obviously for the economic factor they're not going to have a problem. But yeah in terms of business opportunities real wealth does have a wider range of opportunities as you said, but honestly I'm not saying either option is bad.
