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.
Now wealth in material form has become the main thing that everyone continues to look at so that there is no longer a feeling of wanting to build it together when someone wants to get married. Indeed, what you say is not wrong because I also often see many couples who end up divorcing after they continue to have difficulty meeting their increasing living needs. But there are also quite a few married couples who are able to survive and continue to struggle not to separate in difficult conditions like now, because they always look for solutions together when facing problems and don't really care about the wealth they have spent together through life.
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.
This means that you also really like these two things in your life, so that after you choose to be rich in fiat you still like to choose crypto investment even though your efforts to get it are only through fiat. And in essence, people who are rich in crypto are also preferred and paid attention to by many people because now crypto can also be brought into business, be it everyday business or investment business with long-term targets. So whatever you choose will always be good and will not be wrong.
