Are you seriously?
They have Bitcoin smart contracts - look at the site, x11 algo helps to make transactions anonymous and higher profitable mining.
Today we will see how their developers work. Only for work you can judge the team. Personally, I'm more interested in fork work, but not who they have as a developer.
Mining ? Show me one mining pool where u can mining. Look premine coins... For me Segwit 2 is just another altcoin....
