Xtremcoin is an open source highly secured exchange economy, empowering the future of open and online marketplaces. It is used as a type of digital fuel which allows exchange operators to freely run and operate a secured exchange system. The technology is already built and is in production globally and we seek to expand and open up the technology to the world through the Xtremcoin Network and model. It helps increasing the transparency, accessibility and the global penetration of one of the most innovative creation of humanity, exchanges.
Xtremcoin forms an exchange network where participants can share and re-route their liquidity and credit lines and investors have the opportunity to boost launching new exchanges and create new venues for trading globally. Xtremcoin is distributed in the most transparent way following market adoption curve pattern and is distributed on Xtremcoin.com where investors and exchange operators can participate to purchase these tokens.
