If you’re wanting to purchase Tether, there are several options. The simplest method is to exchange USD for USDT on any of the exchanges that allow users to trade USD for Tether. This includes KuCoin, Bitfinex and Kraken.

In addition, users can also buy Bitcoin (BTC) or Ethereum (ETH) with fiat currency from an exchange like Coinbase and then use their BTC or ETH holdings to buy Tether directly from one of these crypto-to-crypto exchanges like CoinW or Changelly.

If you don't have access to any fiat currency but want some cryptocurrencies anyway, another option is to buy gift cards via services like eGifter. You can then use these gift cards at places like Amazon or REI when shopping online; they'll give you instant credit without requiring a credit card number or making payments directly through your bank account.
