Coinone is South Korea's international Bitcoin station, headquartered in Seoul, South Korea, and was established in February 2014. Bithumb remains the largest Bitcoin exchange, with approximately 76% domestic market share. In addition to operating a cryptocurrency platform, Coinone also operates a blockchain-based remittance service.

On September 11, 2017, Coinone announced that Coinone Blocks, its first and the world’s first digital currency offline physical international station, opened in Seoul. The transaction services in the international station are exactly the same as online. In addition, the offline international station also provides face-to-face transaction consulting services and sells USB hardware wallets. The international station is equipped with a Bitcoin ATM machine, and the display screen can also view the market conditions of six major digital currencies in real time and conduct transactions (BTC, BCH, ETH, ETC, XPR and QTUM).

Coinone said that the move was to meet the needs of people who want to trade securely and use tangible services, and said that Coinone Blocks will have the mission of "creating a healthy and transparent data currency ecosystem."
