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?
Yes I've been using USDT for a very long time now and I don't have any negative news on the stable coin, its way better when using the Tron network too, transaction fees are way cheaper than using on ERC20 smart contract
