How much giveaways i have to do to grow up levels?

It's based on the dollars, not the amount of giveaways.

It's not based of the number you gave away, it's based on the amount of CV.

Let me introduce you to a great feature called "Search". It looks like magic, but it's not. Let me show you: http://www.steamgifts.com/discussions/search?q=levels

Got it, thank you guys!

Bear in mind that some games are in bundles, and only have 15% of their values to be counted on your CV. To know which games are bundled (and thus have lower CV) check here : http://www.steamgifts.com/bundle-games
