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 find it very stable and secure to secure the property.
With a crypto that you can use to treat it as dollars in life. I agree they are lacking in transparency about the information in this market,
but perhaps the time they spend in this space is of great value. I see usdt almost as a bridge connecting crypto to real assets.
