I am happy to share with you my little success story on Clixsense.
I joined Clixsense on 1st Dec. 2013 and used to click ads occasionally. By 31st March 2014 ( i.e. after 4 months) my account balance was $2.32 and becoming upgraded member was a distant dream.
However, then I started looking for surveys on regular basis along side clicking ads and this strategy worked very well. I could complete 13 surveys since 1st April 2014 till date and that enabled me to earn $17 required for upgrading to premier account.
Yesterday, I upgraded myself to premium account with available balance. I could have done this much before had I seriously taken note of all available earning options.
However, the important thing is I could upgrade myself through patience and clicking all available ads consistently. This shows anybody can become premier member without investment on Clixsense.
