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.
When you are about to get married, having fiat or crypto money (for example bitcoin), is actually all the same. Because all of them have the same goal in financial terms. Because basically everyone who has fiat or crypto money is sure to cover all the needs that exist in their life. Moreover, when you get married, you will definitely need a large amount of money, for the cost of renting a building and the like. But I think, if you want to get married and there is already a candidate, it's better to get married quickly. Don't wait for the economy to settle down first. Because the most important thing in marriage, is life after marriage. So if you don't have big enough capital, do it with a potluck party, as simple as possible and balance it with the money you have.
And your opinion about bitcoin, in my opinion, is not quite right. Because you think that bitcoin can only be owned by 21 million people. Even though with only 21 million bitcoins, bitcoin can be owned by people all over the world. It's not that bitcoin, which is only 21 million, can only be owned by 21 million people, such an opinion is inaccurate. Because now only people who own and invest in bitcoin, must be more than 21 million people. So you don't get the wrong idea about bitcoin.
