But personally I still trust USDT, for me it is time tested.
There is nothing better than to have your money in fiat, USDT can be freezes on noncustodial wallet, so people that have it do not have full control just like fiat but fiat is secure than stable coins.
USDT was not the safest. USDC and BUSD were safest stable tokens.
But USDT remain like USDC and BUSD in term if safety if they are all fiat backed stable coin.
