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.
So far USDT is still the mainstay of my stablecoin, to protect the value of assets from price fluctuations I only use BUSD and USDT, because in my opinion they are the safest. As for price fluctuations that are sometimes less than $1 USD, they are temporary for a number of reasons which differ in each situation. the thing that makes me feel safe is :
USDT
Every Tether token is 100% backed by our (theter) reserves, which includes traditional currency and cash equivalents, and may include other assets and receivables from loans made by Tether to third parties.
BUSD
BUSD is 100% backed by reserves held in either or both fiat cash in dedicated omnibus accounts at insured U.S. banks1 and/or U.S. Treasury bills (including through repurchase agreements and/or money-market funds invested in U.S. Treasury bills).
