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?
Despite claiming that the Tether token is backed up to the equivalent of 1 USD per token, I am never sure if the usdt developer provides official guarantees so that usdt holders can sue, or to be able to redeem tokens if it is with USD, because I saw on their tether site the sentences : "We do not guarantee the right to be able to exchange Tether for fiat currency". and that means they could get off their hands if something bad happens to the tether price in the market. maybe some people think that usdt is a token that was created as a substitute for usd in digital form and many people feel safe to save their money now in usdt but not for me personally because i see a lot of controversy that has occurred since the initial release of usdt on the market.
