Motivate users to trade. Fortuna supports two modes of trading: PrC and PuC. Under PrC mode, users can launch a peer to peer transaction without any cost of agency. Under PuC mode, users can create new types of derivatives and be the market makers while benefiting from the trading volume of the new derivatives created. 5. Enrich the derivatives market. Users of Fortuna can create all kinds of derivatives with different underlying assets, deal structures, durations, margin ratios and other elements of transactions. To some extent, Fortuna can be a worldwide incubator for innovative derivative tools. 6. Algorithmic regulation and self-discipline.
