I have been playing in tanks for a long time, and making money on it seemed like a tempting proposition for me. I started cooperating with the company "Wargaming". Began to advertise it on my YouTube channel. Referral system was stable and brought quite a good income. As some time passed, the audience of my channel grew and the representatives of Wargaming suggested that I should re-write a partnership agreement. At the moment I am satisfied with everything.
