Deribit, the world's largest cryptocurrency derivatives exchange, aims to expand in Hong Kong, a sign of momentum as the market regulator looks to make the city a hub for virtual assets. The Dubai-based company was drawn to Hong Kong because of its position as an international financial hub and its vibrant community of family offices and asset managers, which are increasingly interested in cryptocurrencies, said Jean-David Pequignot, the firm's chief commercial officer, who is based in the city.
