I know that USDT is the most commonly used stable coin in the market but I dont think it is trustable as each USDT is claimed to be backed by 1 USD but never given a proper audit and also its marketcap which have increased in 1 year from 40B $ to 76B $, do they really have that much USD to back USDT up?
I would prefer more safer decentralized stable coins like UST,DAI and USDC.
