The official group of the doBETacceptBET project, designed to change options' market. Our experience in trading margin options on financial markets, as well as the active use of barrier options in the foreign exchange market, allows us to develop a trading platform based on blockchain and crypto currency technologies. This platform will have its own payment system, which will allow participants to purchase and sell options using the DCA coin token. Thus, participants will be able to buy and sell options. The launch of the trading platform is scheduled for the end of the fourth quarter of 2017. and, judging by the reviews players, our service will attract both speculative and institutional investors. Fundraising and issuance of DCA coin token will help finance the marketing and advertising of the trading platform, as well as the development of technology for a smart contract (logic of the trading system) based on Ethereum blockchain inside the platform. DCA coins will be used for internal settlements between participants in the trading platform with a view to guaranteed payment of the winnings at the expense of the funds of the participant who undertook to pay it. DCA coin token will provide an opportunity to use the technology of a smart contract, to develop a decentralized option market and to enable participants to use all the opportunities on the options market: to speculate, engage in arbitration, hedge own operations.
