Do you think what we currently have with USDT pegged 1:1 with the US dollar is better or are you also a part of the school of thought that thinks $USUAL approach pegging USD0 1:1 to Real-World Assets (RWA) is a better option?
You're probably trying to compare traditional and algorithmic stablecoins. To me, they don't have many functional differences, but their mechanisms are very different.
Traditional stablecoins like USDT and USDC are price-backed by the issuer's assets and exist outside the crypto market. These assets include government bonds, gold investments, commercial paper... This is considered the safest mechanism to date.
Algorithmic stablecoins are automatically pegged to assets within the crypto market and use various limits to ensure value. UST failed but DAI is still very successful, meaning the operating model is really important for algorithmic stablecoins.
Personally, I only approach and use traditional stablecoins such as USDT and USDC. I have no need to experience risk with algorithmic stablecoins.
