Hashkey Group, a crypto investment firm, intends to seek funds at a valuation of more than $1 billion, capitalising on Hong Kong’s digital asset drive to woo potential investors. According to persons familiar with the situation who spoke to Bloomberg News, Hashkey, which operates one of the city’s only two licenced digital coin exchanges, is in early-stage talks to raise $100 million to $200 million. The sale is moving forward, but terms such as size and valuation could alter because they haven’t been finalised, according to the sources, who asked not to be identified because they were discussing private negotiations.
