It has been already announced in the march of this year ( Premium Upgrade - Welcome Ads end ) that the 'Welcome Ads' will be replaced with 1000 AD credits worth $2.40 .
If you have an website/blog or working in any other PTC you can advertise it with clixsense using the 1000 AD credits that you have been provided with for your premium purchase .
