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 ... etc.
Personally, I would prefer to be married to a rich person with lots of fiat reserves compared to cryptocurrencies.
Remember that being rich in cryptocurrencies mean that their resources are somehow unpredictable- if the prices drop in the market, then such person could lose 50% of the total value of their cryptocurrencies. On the other hand, if a person is rich with fiat, at least, the money that she has is stable and she could venture and diversify the investments.
Remember that being rich in cryptocurrencies can be misleading. Until they have converted their cryptos to cash, then that is the only time you would consider them rich to begin with.
Crypto is still a risky asset, its value can disappear quickly, so it's hard to say someone is rich when they hold crypto, especially shitcoins. For me, it is only when converting cryptocurrencies into fiat and tangible assets that it is called our money. If our wealth is still in cryptocurrency and it is shitcoin, then there is no guarantee that our wealth will be maintained long term.
Although we are engaged in cryptocurrency to get rich, it is necessary to be realistic, and if I am a woman and with this question. I would also choose someone with more fiat than crypto.
