There are some cryptos out there that have the problem solved that you are talking about.
So you have one cryptos and buy their coin/token and load up your wallet. Then you can buy something online or in a physical shop or withdraw cash from an automatic teller machine (atm) or pay someone in any fiat currency anywhere in the world to their bank account all from your one wallet which simply converts from your coin/token, for a small fee, to whatever crypto or any countries fiat currency. I think also your coin/token may be even able to convert to pay a person in commodities tokens/coins also , gold,silver,oil etc. I do not think they will cover all cryptos but certainly many of the main cryptos. Maybe in time they could convert to most cryptos , including cryptos that buy/sell shares in the skock market.
The person you are buying from or sending crypto or fiat has no clue what crypto or fiat currency you hold.
I will look up names of some of these cryptos I am talking about and post them at a later time.
Also with new technology pretty soon you will be able to make direct payments across different blockchains. eg from BTC > ETH , BTC > LTC . At the moment you need to exchange one coin/token for the other. In time this will make many crypto exchanges extinct. The space is constantly evolving.
