XTRABYTES is developing a comprehensive modular platform where customizable services in any programming language can be built around their unique POSIGN algorithm. A quick association is to think of XBY as an Ethereum 2.0 of sorts, but with greater scalability, security, and freedom. Simply put, XTRABYTES isn't going to remain in the shadows much longer. For this reason, it should be easy to purchase and sell XBY on quality trading platforms like Bittrex.
Here is more information on XBY from the ANN for anyone who hasn't heard of it yet.
