I think if all countries in the world agree to use crypto in all transactions in all fields. Is paying insurance, shopping, paying electricity bills will be as easy as flicking a finger?
No, because there are different coins for different uses. We are used to this (one for all, centralized), because of fiat currencies, but I think, we are moving to a decentralized world with many choices and opportunities. Are everybody has taste in food, on cars, on vacations, we will have a taste of the tool of transaction settling.
