The company released a statement:
Dear Users, Last night Asia time, we suspected a potential leak on our hot wallets. Therefore, we decided to shut down the exchange and ports in order to minimise further potential losses, and we are conducting a full forensic investigation to identify the root of the issue. This is why Gatecoin’s user interface and API are currently offline. Please be sure that we will do our best effort to investigate, fix the issue ASAP and we will cover for the potential losses. We store 95% of users’ crypto-asset funds in multi-sig cold storage vaults, so your funds are safe. Please accept our deepest apologies for this disruption. We will keep you regularly updated on the progress made by our team. Sincerly, The Gatecoin Team
