be careful with click2dad
first time withdraw, paid
second time withdraw, still not paid (30 days ago)
and i think click2dad paid too small, there's a PTC paid 30x bigger
And which one, may I ask?
CoinAd ?- max 400 sat. ( 2 or 3 ads.)
btcclicks ?- max 60 sat. ... pfff
bitcoinclix? 350 satoshi, (1 ad) + captcha ... pfff
visitbit, visitbtc ...

only minus is 2 mBTC payout, but with free lotto you can reach it quite fast.
PS. try to cancel withdrawal, they changed payout conditions.
be carefull with click2dad.
first time withdraw they pay but second time they didnt pay again.
coinad.com is the best trusteed PTC. I have withdraw 10 times and they pay
