There are other reasons why having stablecoins is useful.
Regular money can’t be transferred digitally. If you want to send money to someone, both your bank and their bank need to speak the same protocol. This isn’t an issue usually but try sending a large transfer (>100k) or sending money internationally.
Stablecoins have the protocol built into it. Just by using a stablecoin, you are able to receive and send the coins digitally to anyone else who uses them.
