On Friday, Yonhap reported that the BTC Holdings Company, which has held 75.99% stake in Bithumb, has signed a deal to sell 50% plus 1 share for KRW400 billion ($354 million) to Singaporean blockchain consortium BK Global.

BK Global is described as a Singapore-based medical group that operates plastic surgery and aesthetic clinics in South Korea and Singapore.
