Watching ads doesn't cost me anything, not even time. I just mute the tab, let the ad happen (if need be) and just watch a Youtube video in the meantime. Or I'm queue'ing up for a League of Legends match and have nothing better to do anyway.
I get Soul gems for things I want, Gamehag gets money, the advertiser can spread the word. Everybody wins (as long as Gamehag gives us what we want, that is, but that is a whole other discussion).
i think they dont have anything to do
thanks for replying

Every game has some quests for which you will receive Soul Gems.
You can exchange your Soul Gems for Steam Wallet top-ups, game keys, CS:GO Skins and other rewards.
