Works in mysterious ways. Nobody knows. It's a huge weird and complicated system. faq!

So guys what's worse people asking this question OR people who ask why they can't give away Dota 2?

I think this question is worse.

No, it's unresolved mystery.

Here's why

...

Try actually reading the site's rules.

You're giving away only bundle keys. That is why.

Ty ... Before posting I had read the FAQ but I did not find the answer ...

Be glad that bundle keys give you some value, they were talking about making them worth 0.

The first 25$ of bundle games are counted as non-bundle. Value above that is only added to a maximum of 20% of your non-bundle contribution.
That means you can only reach a contribution of 30$ with bundle games alone (25$ + (20%*25$)).

Formula:

adjustedbundlevalue = bundlevalue - Min( bundlevalue , 25$ )
adjustednonbundlevalue = nonbundlevalue + Min( bundlevalue , 25$ )

contribution = adjustednonbundlevalue + Min( adjustedbundlevalue , adjustednonbundlevalue * 20% )
