for payment on bux3 upgredation is compulsary?

You don't have to upgraded on bux3 to receive payment but you will get it alot quicker. I am a standard member. I am still waiting on payment looks like it will take 60 days or 2 months to get my $10 I do not upgrage on a site unless they have paid me though and I have not been paid by them yet.

60 working days means about 3 months or more :( that is sad :(

no not compulsory just quicker - standard take up to 60 working days to get paid - upgraded members get it in about 30 working days
