Tether is the only crypto-currency that has guaranteed guaranteed pegged value. Many people wonder why Tether was invented, and it’s actually pretty simple: fiat currency is created through debt, and this debt never gets paid back. People just keep creating more of these currencies without trying to get rid of any of them (always new money-creation). This doesn’t sound like a good idea for a currency does it? So Tether was invented as a substitute for real money where there isn’t enough physical currency in circulation compared with demand — exactly like Bitcoin solves the problem we didn’t even know we had!
