I don't have direct referals, and that's what I will work on in future. I will recommend Clixsense to everyone as reliable site which enables people to earn some cash. Mostly I made my money by doing tasks. What I like the most about Clixsense is that it does not have rented referals like in other PTC sites, which in my opinion are not real people, but bots.
I payed $8 as bank provision, so in about 3 months I made $110. I plan to withdraw my second cheque around June 2015, and hopefully it will be at least $300.
Good luck to everyone!
I don't know how to post images from the PC (it only has option for URL) so I cannot post the payment proof here.
