I think as of now, there is no chance for us to buy insurance using crypto especially a lot of countries doesn't support cryptocurrency, but if there is any, I think they will not still allow it given the fact that no one really owns the crypto and it is volatile, so insurance company will stick to fiat money when it comes to insurance. But in my opinion, buying insurance using cryptocurrency is possible in the near future knowing that a lot of people now are interested on having cryptocurrencies as their investment.
