The team developed a full bitcoin exchange of which we are very proud. The front end is in PHP and Squarespace and the backend is in MySql. The project involved a number of challenges in security, blockchain development hardware architecture and system integration. Please see our work!

Investors can sell their bitcoin, have their profits hedged through derivative contracts and reinvest. See https://www.chicagobitcoinexchange.org/investors-wanting-to-sell-bitcoin/

Also, but not visible, is a great employee compensation scheme that rewards employees immediately in bitcoin for sales by the company.
