Asian-based cryptocurrency exchange HashKey Pro has reportedly applied for a licence upgrade to the Hong Kong Securities and Futures Commission (SFC). The exchange is currently restricted to trading only a few digital currencies like bitcoin, ether, tether and USD Coin, but it plans to offer a wider range upon licence approval. It targets to begin offering services to small-scale investors in the upcoming weeks. This application follows an announcement by parent company HashKey Group of plans to raise $100-$200 million to leverage the recent introduction of Hong Kong new licensing regime for Virtual Asset Service Providers.
