If I make a giveaway from a bundle game, how much CV will I recieve?

Full CV up to $25, then an additional 20% of non-bundled CV (auto-adds you up to $30, then caps out until you give a non-bundled game).

depends on the amount the game is worth. 100% CV up to 30USD w/o any none bundled games. Check the Faq FOR A DETAiled breakdown.

At your current state, $30 or the value of the game, whichever is lower.
