USDT (tether has totally regained his dollar peg after over 2 months of trading below $1 .It lost its peg after LUNA's collapse ,when it came down to $0.97 and it was sold at FIAT or other stablecoins.
So saying saying that USDT has regained its peg , we can see traders trusting the market and it will bring more capital injections into BTC ,ETH and alts ,which are likely reaching new mid term high until the end of the year.
if you compare USDT with UST, it is clearly very different. USDT is made with stable authenticity of coins,
and USDT is fixed based on USD, more marketcap than UST and USDT there is no project that breaks coin stable algorithm,
we know UST incident scares traders back to stable coin, but I recommend not to be in stable coin by project, such as USDN
