If I grab your message very well, you're trying to know if people prefer marrying people that are rich in cryptocurrency or fiat. Right?
I think wealth shouldn't be a basis for going into marriage with someone, for just like many marriages we have seen these days such couples don't last in their marriage.
A pragmatic individual considers financial aspects when choosing a partner. Wealth serves as a reflection of one's success in diligently and cleverly pursuing their work. A man should, at the very least, possess skills that enable him to work hard and survive alongside his partner. Diligence is a common standard that must be upheld, while handsomeness, wealth, and physical appearance merely serve as supplementary criteria.
Marrying a wealthy individual is an endeavor, but if you cannot find a wealthy person, then at the very least, marry someone who works hard. Wealth shall crumble under poor management, yet with the steadfast foundation of hard work and intelligence, an individual's wealth shall continue to flourish.
