Sure you are watching champs of the cs:go universe!.. I mean CSGO events in view of cases dedicated to these events on web-store these boxes to spin! I am sure these cases are more hopeful and profitable than others. While case opening on web-service I win AWP Asiimov for $27 and M4A1-S Hot Rod for $80 from the case called dream hack.
From then onward I use to purchase boxes which are editing to single events like tournaments. In such a manner I caught Gut Knife Lore... I spinned case dedicated to ESL Pro league on Open cs:go... M4A4 Poseidon I win from the box another time!.. This box is only $ 4,45 now and I am sure it could give me much!
