Bithumb is the most popular cryptocurrency exchange in Korea and it also can be found among the top crypto-exchanges in different international rankings. It is a global leader in trading bitcoins and it also accepts a number of other cryptocurrencies. Don’t be afraid if you see its interface in Korean language. This platform supports six languages and English is one of them. Bithumb offers only spot trading, so if you plan to trade on margin, you will probably have to choose another exchange, like Kraken or GDAX. You will also go to another place if you need advanced trading tools or if you are not ready to pay international transfer fees, being based outside of South Korea.
