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 USDT tokens, I don't think these tokens are a coin scam. usdt has a great value, and even the token price is as high as $ 1 per unit. But the problem with USDT is that the price always looks normal, the ups and downs are like having a small percentage so that it is less attractive in the market.
