We are working very hard to build the exchange. Unfortunately, as with any big and ambitions project, bugs will be found, and delays will occur. The Digitex Futures Exchange is a complex beast, involving an engine that must be super-fast, market makers that add liquidity and break even, multiple markets, non-custodial accounts, and complicated Smart Contracts. We will also be integrating the Plasma update to the Ethereum network. As you can imagine, this is a huge undertaking and a massively complex project.
We have missed deadlines, and for that we apologise, but it's difficult to predict every eventuality and outcome. Rest assured that we are fully committed to the project, and will overcome every obstacle and set-back that occurs.
