I don't whine about anything. I like transparent stuff. You answer has proved that 100 OUSD can not be swapped to 100 USD. If I use OUSD-Gbyte then Gbyte-BTC and BTC-USD route afterwards I will get far less than $100. That is why I would rather consider this particular asset as algorithmic asset which remains relative "stable" within its bounded algorithm but not in the real life.
The word is bonded, not bounded. And there is GBYTE-USDT market too, just low volume. Just because USD stablecoin doesn't have direct fiat off-ramp, doesn't make it algorithmic stablecoin. If you have to go multiple pairs until getting back into fiat, you might get back even more than 100 USD too, this has nothing to do about what typr the stablecoin is, but all about what markets it is being traded on.
You are making up new words, there is not such stablecoins as Bounded stablecoins. The prices that Bonded stablecoins use are not bounded, but bonded - means that the prices are bonded with some other value (such as supply) on a bonding curve.
There are algorithmic stablecoins, but these are usually not backed by anything and just inflate or deflate their supply to keep the peg.
Bonded stablecoins are as algoritmic as any AMM exchange - it's not overcollateralized, it doesn't have margin calls and it doesn't have liquidations.
