Only 1% of population cannot decide which currency to use to trade all the assets, yes it can be a good start if you do it on personal level, but I doubt it will be a very successful thing until a lot of people join it. Moreover the problem is that the currency you are using to buy these assets is itself too volatile, it's pricing itself has been too uncertain, buying assets using such a volatile currency is itself a pain in the ass.
It's really annoying when we let go of these assets to buy things we want to have. Crypto price fluctuations are indeed a risk that must be realized, prices will change quickly and if you really don't think about the value of crypto to Fiat, of course, using crypto is the best choice.
I still rely on Fiat and use cryptocurrencies too. Fiat and Crypto can still coexist.
Crypto currently has many pros and cons and several countries regulate according to the conditions in each country.
