As for me my biggest asset was fiat until I realized how bad deal I'm getting, how much I was screwed by going to another country and saving all my money in fiat. That's why I was open to Bitcoin early on. For you, as your biggests assets are in real-estate, you're not in the danger that most people in the world are.
Crypto communities spread FUD about fiat all the time. Some of it justified.
But equally justified is looking at the -real- value that BTC and other crypto assets offer.
(Disclosure: As many people here on HN, I entered into the crypto space during the 2016-2017 rally. Still get paid in fiat. And my biggest assets are in real-estate.)
