Where is the white paper? On the homepage https://getsirius.io I can only find the position paper. And on the github repository they didn't even bother to change the documentation from the original Bitcoin client, from which qtum was initially cloned:

And looks like it is not only my opinion, price drops like a stone. Probably the devs are dumping it, too.
