eBettle is currently at the bottom of our ranking, so I think that it's really not worthwhile to focus on them.
I didn't even heard of this website.
Most of the websites that are listed, I'm not really familiar with them.
But the most popular ones here in forum are not even listed to that "best" e-sports website.
how about sportsbet and Onehash mate.
Include also nitrogensports.eu
