USD Tether is a Bitfinex issued ERC-20 token which is claimed to be backed by dollar at 1:1 ratio. There are controversial opinions about this and some say it's a scam.
Do you trust USDT or believe it might be a scam?
I really believe in stable coin, namely USDT because this coin has a ratio of 1: 1 to the original USD, so until now I still keep my money in USDT in some of my market wallets. and I never worry if my money will decrease in my wallet because USDT is a stable coin. but in cryptocurency, everything can change at any time and no one will be able to predict it.
