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!
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.
It's pretty funny that you believe that when you die nobody will make a tomb for you, very funny, do you know that if a dead body is lying dead on the ground for some hours, all the people living within the place will start getting sick? Every dead bodies have their places, they can't be on the ground where people are living, if you died and you have no kids or family that can bury you, someone have to do it, for the health sake of people living in that surrounding.
Things have gotten to hard in the world today that you will need money to survive, its true that no female will want to live with such a man who has no dream and I don't blame them, it can be very hard to get a partner who don't give a shit about the world and that's the type of people that makes a good life partner, you need a lot of luck to have such people in your life.
Still I would advice any man to never marry anybody simply because you have a lot of money, having money can be a curse at times, it is better to pretend and live a lower standard lifestyle to attract those that will love you for who you are and not your money.
