paid-to-click sites have never been worth the time and effort, let alone spending money in them! and the site(s) paying in bitcoin are no exception either. all of them also have traces of Ponzi schemes in them as they "sell" you something (ie. referrals) to make more money but what happens is that they are paying you back with the same money you paid them.
Never worth the time or effort... whatever.
I withdrew almost 3.4 BTC from btcclicks.
It's no ponzi, it's an advertising service. I happen to like paid to clicks.
