It is correct that Tether(USDT) has more trading pairs and is a popular choice for crypto traders, early Tether(USDT) is used for liquidity when it was added to BitFinex exchange in January 2015
In 2019 Tether website claimed that stablecoin was backed by reserves in traditional currency and cash equivalents site states that “All Tether tokens are pegged at 1-to-1 with a matching fiat currency and are backed 100% by Tether’s reserves.”
Adam Carlton, CEO of crypto wallet Pink Panda, says Tether’s history of being transparent about how the coin is backed hasn’t always been clear
Other crypto experts say it’s somewhat accepted that Tether isn’t “fully” collateralized in the crypto marketplace. And that it was an issue of controversy more than a year ago.
At first, I prefer tether(USDT) rather than BUSD but after my bit of research at google about tether history, I found the above thaught of people on tether & one worried statement that “The risk would be Tether losing its value or the staking platform chosen is not legitimate,”
After that I change my mind now I will use BUSD for long-term investment & staking Tether is only good for trading not for the long term or staking because it has chances to lose its value at any time like previous. BUSD is much more secure than tether(USDT). but It is my opinion.
