I think the stablecoin I have trusted is USDT because USDT is still in the top 3 based on coinmarketcap. although there are many negative assumptions about USDT but I still hold USDT to this day. maybe BUSD has won the trust of users because BUSD is a product of Binance and is fully supported by binance which has become the largest exchange market today. but I trust USDT more until now.
