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.
Marry someone who is sincere with you and don't think about wealthy or poor person because getting care from your partner will be better for you than money. Those who leave their partner because of financial issue should remember that person can be financially stable anytime but if you lose a sincere person then you will always regret for it.
Encouragement make a bond between partners strong so I will suggests that whenever your partner needs you, be available and if you think that money can strengthen your relationship then its wrong because there are numerous individuals who are financially stable but their life is not happy. Actually you can earn money anytime but you cannot find loyal person all the time.
