In life you have to be rich of something, or nobody want to marry to you, and have build a family with you, you would be foreveralone, and the media would constantly mogging you over and over again for being foreveralone to remain you. And your mum would constantly tell you if you don't get married nobody would take care of you when your aged. Nobody would make a tomb for you, and when you died you would go to afterlife with empty stomach and would suffer straving too in the afterlife. That must be a lot of hurt! ouch!
I have never been scared of staying alone because there are so many things to do apart from getting married. I have also nursed the idea of adopting children if I didn't meet any woman that is compatible with me. Your mother just sounded like an average African woman. But I don't consider the future because I might not have control over it. How am I sure that I will ever get old? How are you sure your spouse will not die before you? The dead are conscious of nothing and don't care if it was buried or eaten by animals. And the dead don't need food for anything.
So back to question. which is preferred? Married to fiat rich or crypto rich? Although crypto can be created at the comfort of your basement, also the value would plummet quickly to near zero too. Do you think in your life, you would ever see someone marry to crypto rich? btw recent news about ftx being rejected to sponsor a superstar due to it is unregistered tell me marry crypto rich might be a distance dream. Also there would be only 21m bitcoin existed, only 21m couples would be able to married rich. When there is billions of population, a lot of couples may not marry rich, due to unequal distribution, some of the crypto super rich would married hundreds of thousand more.
If you marry because of money, you will be disappointed because it comes and goes. Marrying a crypto millionaire is not a bad idea if you are comfortable with his character. I don't also think that cryptocurrency is the only sector that makes people millionaire, so women still have choices.
