The extended answer to the question is that while Poloniex is the only gateway available, its long confirmation time can be a hassle. To avoid this, consider using a different exchange that has faster confirmation times, such as Binance. Binance is a popular exchange that offers a variety of trading options, including crypto-to-crypto trading. It also has a fast confirmation time and a user-friendly interface, making it a great option for those who want to trade quickly and easily. Additionally, Binance offers a wide selection of coins and tokens, allowing users to access a range of different markets. Ultimately, while Poloniex is the only gateway available, there are other exchanges out there that may be better suited to your needs.
