Stablecoin designed on the eth network. To be able to use it you must have an eth amount for commissions. Commissions on eth are currently higher than those on BTC. An abnormal amount of tether is created every week, for which they have no cover. Litigation has been initiated against them. You have much better alternatives than it, you can use real dollar on bittrex, not this digital one. One of the greatest evils that can befall the crypto world. If you keep it on exchange offices, at least you can easily get rid of it for any other currency, since there is literally a pair for every coin with it.
