Well, I've use to get two or three ads each visit. And have visited them almost every day since the middle of march. So far my amount there is at 0,00376600 BTC
Has anyone ever get anything from bitcoin4you.net? 
The withdrawal rule is ...
Very limited and restricted adds views daily + WTF withdrawal rule.
Minimum payout is 0.004 BTC - fee. -> NEW! (before 0.005)
We will reduced you amount for transaction fee (0.0005 BTC)
I'm not even sure how long it will take to get into 0.004.

It gets longer and longer to reach that minimum withdrawal limit but I have gotten a fair amount from this site over the months I have been checking it.
Each person will find their favorite sites depending on things like the trouble they have to go through to get a prize and how long they have to wait
before being able to withdraw etc.
Of course waiting until one has a larger amount before withdrawing is advantageous to not only the operators of these sites but the users as well.
