Actually, I don't know where I can buy tether with Fiat where I can deposit via wire transfer in the U.S?
Seems like Gemini, coinbase don't support tether. Is there any other option?
In case you haven't gotten an answer; Kraken. They support Tether, but honestly I haven't used their service, so it's not a recommendation. I would just use Coinbase or Bitstamp to buy BTC then send it to Binance to trade for whatever.
