I think the stablecoin I have trusted is USDT because USDT is still in the top 3 based on coinmarketcap...
The large capitalization of a stablecoin cannot be a guarantee of its security. After all, any issuer of a stablecoin can print an unlimited amount of its stablecoin, which can increase its capitalization several times at once. Here, the reliability of the issuer behind this stable coin is more important, and what reserve assets are used and their quantity to support a stable exchange rate.
