Peoples believe in using USDT and BUSD as stable cryptos. The last audit for Tether was on October 11, 2021, however they did not mention the number of coins from the audit. It is audited by Fairyproof. If I'm not mistaken, it was previously audited by CertiK. But the question is whether Tether has USD reserves as much as USDT in circulation today? Likewise with BUSD with a supply circulation that continues to grow. CMC did not release the audit team information of the stable coin BUSD. Maybe BUSD got the trust because of the developers who sourced from the owners of Binance.
