Youbit

Youbit operated as a cryptocurrency exchange based in South Korea. Its core service was facilitating the buying, selling, and trading of digital assets for users. The platform provided wallet services that allowed customers to store cryptocurrencies on the exchange. It served primarily the South Korean market, though the exact geographic reach of its user base is not detailed in the source. As a digital currency exchange, it participated in the broader ecosystem of blockchain‑based financial services.

Youbit distinguished itself by experiencing two separate cyberattacks within an eight‑month span in 2017. The first breach, attributed to North Korean cyber‑spies, resulted in the theft of approximately 4,000 bitcoins. A second attack occurred later, leading to the loss of about 17 % of the exchange’s total assets. Despite the intrusions, a portion of funds remained secure because they were held in an offline wallet, limiting the attackers’ access. Following the incidents, the exchange filed for bankruptcy and customers ultimately received roughly 75 % of the value of their holdings.

The publicly available sources do not disclose Youbit’s ownership structure or any parent or subsidiary relationships. Consequently, details about whether it was an independent entity, part of a larger conglomerate, or backed by specific investors are not provided. The headquarters location is explicitly noted as being in South Korea. No further information regarding regulatory licences, corporate governance, or affiliations is present in the given material. Therefore, the profile is limited to the confirmed facts about its services, the cyber incidents, and its South Korean base.
