I am a premium member but my paid to clicks is only 10 PTC a day.
Is this real?As I know this is the no.1 site but how is that?

I find it varies from day to day. Being a premium member does not necessarily give you more ads. I read that in the notes before I paid, it does however give you a better bonus on the surveys and offers and that's where I find I am making a bit more.

You can catch a lot more PTC ads per day by installing the toolbar, it will alert you when an ad is present. I get from 25-30 ads a day.

only 4 ads are guaranteed daily for every premium members. the rest of additional ads that you can get depends from advertiser who buy ads through ClixSense. if your country is being targeted by the advertiser then you will be able to get those ads if not, so no. because advertiser who buy ads through ClixSense have the control and option for which country they want to advertise their ads. i suggest try to complete your daily checklist bonus list. do some offer and task if you can and if you have. that is where you will be able to get the most out of your premium membership.

for any additional info about premium membership:

Best I can figure, the big money comes from referrals.
I don't have any actives at the moment so my daily is pocket change.
With an adequate down-line, it doesn't really matter how few ads you click so long as you make the Daily Checklist!
